Abstract

The spent COD test solution has unique characteristics, i.e. small in volume and discontinued in production. However, it contains hazardous elements to environment such as heavy metals, i.e. silver, mercury, iron, and chromium, which could be having an economic value if can be reused. This research was subjected to the recovery of silver element the spent COD test solution using electrolysis method. The anode used was made from platinum sized 1 x 1 cm2, whereas copper was used as the cathode. The optimum silver recovery using the artificial waste of Ag2SO4 was 19.93% and the reaction rate constant value (k) was 0.0363 /minute from initial silver concentration of 199.375 mg/L to became 159.64 mg/L. This result was obtained on the experimental conditions of 5 cm electrode distance, 1 x 3 cm2 cathode surface area and DC supply voltage of 6 volt. The experiment using the spent COD test solution was carried out at electrode distance of 5 cm, cathode surface area of 1 x 3 cm2 and DC supply voltage of 6 volts. The silver recovery was 47.19% from initial silver concentration of 204.375 mg/L to be 107.92 mg/L and the reaction rate constant value (k) was 0.1053 /minute. The results showed that the increasing in DC supply voltage and the reducing in the electrode distance would increase the silver recovery.

Abstract

Polycyclic Aromatic Hydrocarbons (PAHs) are ubiquitous pollutants formed from both natural and anthropogenic sources. Produced water of crude oil industries contains PAHs, which in high concentrations could pollute the environment. Saline water environment model used in this research was an aerobic reactor which contains sediment collected from the estuary of Mahakam River. The sediment bacteria were first activated by glucose and toluene before it was exposed to the PAHs compound. Three PAHs compounds observed were naphthalene, anthracene, and phenanthrene. The result showed that it was difficult to determine the PAH degradation rate in the water compartment, because the PAHs were volatile and easily deposited. The degradation rate of naphthalene in the sediment compartment was the highest when compared to anthracene and phenanthrene. Furthermore, phenanthrene was the most undegradable compound.

Abstract

Abstrak: Secara umum, air limbah industri pulp and paper mengandung produk ekstraktif, karbohidrat, dan lignin. Lignin dan senyawa chlorinated organic merupakan senyawa utama yang menjadi concern dalam potensi pencemaran lingkungan. Pengolahan biologi secara konvensional hanya dapat mengolah sebagian senyawa organik yang terkandung dalam air limbah karena beberapa senyawa dalam air limbah industri pulp and paper merupakan senyawa persisten. Advanced oxidation process (AOP) merupakan alternatif dalam mendegradasi senyawa resistan yang terdapat dalam limbah cair industry pulp and paper. Prinsip pada proses AOP adalah pembentukan hidroksil radikal (OH*) yang merupakan molekul dengan kemampuan oksidasi yang sangat kuat sehingga dapat mendegradasi senyawa organik kompleks menjadi CO2 dan H2O. Salah satu teknologi AOP adalah O3/H2O2 (peroxone). Penggunaan metode ini lebih efektif jika dibandingkan dengan penggunaan O3 atau H2O2 secara sendiri-sendiri Pada penelitian ini akan dilakukan proses AOP menggunakan O3/H2O2 untuk mendegradasi lignin. Variasi feeding rate ozon, H2O2, dan waktu dilakukan pada sampel limbah cair untuk mengetahui kondisi optimal. Hasil menunjukkan bahwa penambahan dosis H2O2 pada proses ozonasi dapat meningkatkan efisiensi proses. Namun pada konsentrasi H2O2 berlebih dapat menjadi scavenger sehingga menurunkan efisiensi proses. Kondisi optimum diperoleh pada feeding rate ozon 26,7 ppm/dtk dan dosis H2O2 selama 2 jam pada pH asli limbah (7-8). Penyisihan COD pada kondisi tersebut sebesar 28% dan penyisihan lignin sebesar 88%. Biodegradabilitas air limbah menunjukkan peningkatan. Rasio BOD/COD meningkat dari 0,11 menjadi 0,33. Kata kunci: Advanced Oxidation Process (AOP), ozon, hidrogen peroksida, lignin Abstract: In general, pulp and paper wastewater contain extractive products, carbohydrates and lignin. Lignin and chlorinated lignin are the main compounds that could be potentially pollute environment. Conventional biological treatments only treat organic compounds partially because some organic compounds in pulp and paper wastewater are persistent organic compounds. Advanced oxidation process (AOP) is an alternative to degrade resistant compounds that contained in wastewater from pulp and paper industry. The principle of AOP is formation of hydroxyl radicals (OH*) which is a molecule with a very strong oxidizing ability that can degrade complex organic compounds to CO2 and H2O. O3/H2O2 (peroxone) is one of AOP's technologies. This method is more effective then uses O3 or H2O2 alone. This study conducted AOP process using O3/H2O2 for lignin removal. Variations of ozone feeding rate, H2O2, and reaction time conducted to determine the optimal condition. Results showed that the addition of H2O2 doses on ozonation process can improve the efficiency of the process. But the excedd concentration of H2O2 could be a scavenger thus reducing the efficiency of the process. The optimum condition obtained in the ozone feeding rate of 26.7 ppm/sec and 100 mg/l dose of H2O2 for 2 hours at the original pH of wastewater (7-8) with 28% COD removal and 88% lignin removal. Ozonation combined by H2O2 increased biodegradability of wastewater. BOD/COD ratio increased from 0.11 to 0.33. Keywords: Advanced Oxidation Process (AOP), ozone, hydrogen peroxide, lignin

Abstract

Graphene Oxide (GO) based adsorbents have attracted much attention from researchers because there have been many reports that they are effective for removing dyes from aqueous environments. That is because GO has good mechanical, electrical, optical and chemical properties, so graphene and its derivatives, such as graphene oxide, have been used in various applications in the field of environmental management. Modifying GO into nano size is an effort to improve its performance in removing dyes. This review uses a database from Science Direct, Google Scholar and Springer, which was screened using graphene oxide, pigments, adsorption and nano adsorbent. The performance of the nano adsorbent showed quite good results in the removal of dyes. The isotherm model suitable for adsorption varies between Langmuir, Freundlich and Redlich-Peterson isotherms. Pseudo-second-order (PSO) is the best model to explain the adsorption process kinetics. Nano-adsorbent modification can be reused at least five times with a reduced adsorption capacity of 4-8%. Studies related to adsorption with GO-based nano adsorbents show promising results in pollutant removal. Still, aspects such as synthesis method, surface functional groups interaction and dye ions and the stability of synthesis products need to be investigated further.

Abstract

Dyes are becoming increasingly prevalent in wastewater, and their presence caused serious threats to the environment. One of the most widely used dyes is methylene blue which has been used in the textile industry to dye cotton, wool, and silk. As a solution to this problem, using biomass (usually considered agricultural or plantation waste) as activated carbon is an important issue. Because based on previous studies, these materials are not only abundant and affordable but also have high efficiency in removing dye. Therefore, this paper will provide a further review of the latest research on the use of activated carbon from biomass as an adsorbent for methylene blue, which includes the conversion process of biomass into activated carbon, the mechanism of methylene blue adsorption, the factors that influence adsorption process, and the characteristics of activated carbon. In addition, it also reviewed the implementation of nanotechnology on activated carbon from biomass to adsorb with methylene blue.
