Abstract

A recovery study of phenol with Polymer Inclusion Membranes (PIMs) needs to be evaluated to determine values of transport kinetic parameter, level of stability, and selectivity of the membrane. This paper describes results of the evaluation of phenol transport using PIMs with polyeugenol as a carrier. PIMs were made by mixing polyeugenol, dibenzylether, and polyvinylchloride in a solvent (tetrahydrofuran) then printed in a container with diameter 4.5 cm and allowed to vaporize for 72 hours. Further evaluation studies are conducted at pH 4.5 with various parameters, among of them are various times that were taken to identify parameters of the transport kinetics of phenol, membrane stability, characterization, and testing of membrane selectivity by comparing transport of phenol with another compound, in this study chromium is used. This study results in calculation of values of transport kinetics of membrane permeability obtained at 8.8 x 10-5 m/s, flux value of 9.512 x 10-4 g/m2s, and diffusion coefficient of 3.826 x 10-11 m2/s. Repeating use over three times, 48 hours, indicates reduction in power of phenol transport by 70.81%. While selectivity test indicates that membrane is used more selectively against phenol than chromium metal. Based on study results, phenol transport effectiveness using PIM with polyeugenol as carrier is 91.4% in optimum condition.

Abstract

The expansion of the global textile industry has resulted in a decline in environmental quality. Environmental pollution resulting from textile dye waste may include heavy metals and dyes, which exhibit carcinogenic and mutagenic effects. Many studies have been done to reduce the harm of dyes. Extensive research has been undertaken to mitigate the detrimental effects of dyes. One cost-effective approach for managing dye pollution is the adsorption of methylene blue using sulfuric acid-activated teak sawdust. Teak wood sawdust, a byproduct of the furniture industry that is abundant and underutilized, contains active sites within its constituent compounds, including cellulose, hemicellulose, and lignin. This study was designed to determine the ability of teak sawdust to adsorb methylene blue. In this investigation, the biosorbent will be characterized using fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and scanning electron microscopy-energy dispersive X-ray (SEM-EDX) to analyze its active sites and surface morphology. Additionally, the study aimed to elucidate the impact of variation contact time, pH solution, and alteration in methylene blue concentration on the adsorption capacity for methylene blue, employing a UV-Vis spectrophotometer for measurement. The research results demonstrated that optimal adsorption occurred at a contact time of 30 minutes and a pH of 6, with the adsorption efficiency reaching 99.67% as a function of contact time. The kinetic study was modeled using a pseudo-second-order approach, with a kinetic constant of 79.71 g mg⁻¹ min⁻¹. The maximum adsorption capacity was 1.351 mg g⁻¹, the n value was 1, and the percentage of methylene blue adsorbed reached 99.88%.

Abstract

ABSTRACT. Phytoremediation with mono and polyculture systems of giant salvinia (Salvinia molesta) and water spinach (Ipomoea aquatica) plants for the treatment of batik wastewater has been carried out. This research aims to study the effect of giant salvinia and water spinach plants in reducing pollutant levels in batik wastewater, determine the order kinetics of Cu, TDS, and BOD reduction in monoculture and polyculture systems, and determine the effectiveness of Cu, TDS, and BOD reduction in monoculture against polyculture system. The research methodology included two main treatments, namely phytoremediation and data analysis. Phytoremediation was carried out by varying the combination of water spinach and giant salvinia plants with ratio of 0:100, 50:50, and 100:0 with a total plant mass of 100 gr. Analysis was conducted based on spectrophotometric and gravimetric principles. The results of the analysis were tested for significance by ANOVA test. Research data showed that polyculture of giant salvinia (Salvinia molesta) and water spinach (Ipomoea aquatica) could increase the effectiveness of reducing Cu metal by 91%, dye by 90%, and TDS by 36%. While polyculture system has better effectiveness in reducing Cu metal, TDS and dyes concentration than monoculture system, but the difference in effectiveness is not statistically significant. Keywords: Batik wastewater, Ipomoea aquatica, mono and polyculture, phytoremediation, Salvinia molesta.
