Abstract

Final Disposal of waste at Air Dingin Padang City using open dumping system is expected to negatively affect the groundwater and surrounding waterways. Research on the content of heavy metals in landfill water flow in the Air Dingin were made in 2 (two) times that were before the rain and after the rain, then the results were compared with the applicable standard. The content of heavy metals Pb, Cu, Zn, Cd and Mn in Final Disposal (TPA) of waste at Air Dingin Padang City were 0.01-0.17 mg/L,  0.005-0.025 mg/L, 0.0-0.7254 mg/L,  0.0-0.011 mg/L, dan  0.0-0.966mg/L. Pb concentration exceeded the quality standard KEPMEN LH 51 in 1995 leachate pond, while the flow of water and monitoring wells Pb metal content exceeds the quality standards PP.RI.No.82 on 2001 and Mn outlet river  exceeds the quality standards PP.RI.No.82 on 2001. In population of all heavy metals well below the quality stanadard PP.RI.No.82 on 2001. The content heavy metals was affected by the distance of the location of waste, the pH value and after of the rain water around the landfill waste.

Abstract

Selectivity of Cu(II) transport from the source phase containing Mg(II), Ca(II) and Sr(II) into the receiver phase had been researched by using oxine as carrier and Sodium Dodecyl Sulfate (SDS) as additive through bulk liquid membrane.The efficiency of the method depends on parameter (the pH of the donor and acceptor phase, effect of carrier concentrations, and time of transport). The selectivity of the method was assessed by performing the single, as well as the competitive transport experiment of Mg(II), Ca(II,) and Sr(II) ion and then Cu(II) percentage which was transported to receiver phase 99.98% and residue in source phase do not detect. The measurement was done to both of source phase and receiver phase by using Atomic Absorption Spectrophotometer (213.9 nm).

Abstract

Pengaruh aktivasi dengan KOH dan NaOH terhadap performance TiO2/C berpendukung keramik sebagai elektroda superkapasitor telah diteliti. Sintesis sol TiO2 dilakukan dengan menggunakan metode sol-gel. Membran keramik sebagai template penumbuhan TiO2/C yang diaktivasi dengan KOH dan NaOH disiapkan sebagai bahan elektroda superkapasitor dengan menggunakan elektrolit hidrogel polimer yaitu polivinil alkohol sebagai separator dan asam fosfat (H3PO4) sebagai elektrolit. Pengaruh aktivator NaOH memberikan peningkatan kapasitansi 1,5 kali lebih besar dibandingkan dengan aktivasi KOH. Nilai kapasitansi dengan aktivator NaOH adalah 14540 nF menggunakan konsentrasi elektrolit H3PO4 0,5 M dan waktu pengisian 30 menit dengan nilai konduktivitas sebesar 45,4 x 10-5 S/cm

Abstract

This research is intended to learn inhibition efficiency of mild steel corrosion in peat water using two type ofchitosan. First chitosan is without treatment and the second one is synthesized by ionotropic gelation method andthen is characterized by Fourier transform Infrared spectroscopy (FT-IR) and Scanning Electron Microscopy (SEM).Diameter of chitosan porous is about 500 nm which is measured based on morphological photo using SEM withinhomogeneous porous shape and porous distribution is unsmooth . Effect of chitin and chitosan on the corrosionof mild steel in peat water is studied using weight loss method. It is found that corrosion inhibition efficiencydepends on peat water pH, inhibition technique and interaction time. The results show that inhibition efficiency ofchitosan without treatment and with treatment are 88.73% and 93.32% respectively. The inhibition is assumed tooccur via physicsorption of the chitin and chitosan molecules on the metal surface. The Langmuir adsorptionisotherm is tested for their fit to the experimental data.

Abstract

Carboxymethyl chitosan (CMC) was synthesized with different methods by reacting chitosan with monochloroaceticacid in the presence of sodium hydroxide under variation conditions. The above samples were characterized byFourier transform infrared spectroscopy (FTIR) and soluble in water in range of pH. The CMc were soluble in watera wide range of pH and applied as corrosion inhibitor for steel in water. The inhibiting influence of CMC was studiedby potentiodynamic polarization method. It was found thad corrosion rate was dependent on water pH and CMCconcentration. The results show that optimum the inhibition efficiency at pH 5 and 1 ppm concentration CMC, i.e.,77%. The adsorption of used compound on the steel surface obeys modified Langmuir isotherm. Polarizationmeasurement show that the CMC acts essentially as a anodic-type inhibitor.

Abstract

Structure and size of titania nanoparticles have been modified with doping the transition metal (FeNiand CuNi) and controlling the calcinations temperature. Gel and M-TiO 2 powder were characterized byFT-IR showed the changed in intensity at 4000-400 cm-1. TG-DTA curve show the weigh of sample wasdecreased with the increasing of temperature 25-800°C. XRD pattern used to identify the titania structureshows the highest intensity of anatase at temperature calcination as 500°C. XRD of FeNi-TiO 2 and CuNi-TiO2 FeNi 10.5-41.9 nm and CuNi 12.1-33.5 converted using Debye-Scherrer’s equation and TEM analysisthe distribution of crystal size as FeNi-TiO2 and CuNi-TiO2 10-15 nm. SEM has shown that morphology ofdifferent surface from the FeNi-TiO 2 and CuNi-TiO 2 at different calcinations temperatures. Titaniacomposition can be determined by EDX analysis give as FeNi-TiO2 1:1, 97.01% and CuNi-TiO2 1:1, 94.63%respectly. The surface area has been determined by BET as FeNi-TiO 2 was 64.38 m2/g and CuNi-TiO2was 40.9 m2/g.

Abstract

It Has been studied the preparation of Titania thin film on glass plate by dip-coating method and their photocatalityc activity test in peat swamp water. This study is performed by using TIP as precursor and DEA as aditive in isopropanol. The addition of DEA affect the stability of titania solution. The titania thin film was made by dip-coating method on glass plate. The glass plate was coated on to titania solution, then dryed at 110 C for 10 minute and at 500 C for 30 minute. The titania coating on the glass plate was made by varying the titania concentration : 0,5 M ; 0,75 M and 1,0 M. Analiyzing of the products by XRD shown that the titania coating on the glass plate are in anatase form. By visual analysis an photo optic, the best film on the glass plate that is coated with titania 0,5 M solution. Based on the glass plate that is coated with titania 1,0 M solution with peat swamp water shown relative good (68,26%) fot the irradiation during 24 hours.
