Removal of methylene blue from waste water using micellar enhanced ultrafiltration.

摘要: Abstract Ultrafiltration of micellar solutions containing sodium dodecylsulfate (SDS) and oxyethylated coconut fatty acid methyl esters (OMC-10) their binary mixtures were studied used to recover methylene blue. This was achieved through solubilization in mixed negatively charged micelles. Under the experimental conditions used, no significant fouling membrane comprising cellulose, polyethersulfone polyvinylidene fluoride observed, with retardation ultrafiltration. The introduction a nonionic surfactant SDS reduced critical micelle concentration micelles then surfactants permeate, i.e., from 8.3×10−3 M for 2.0×10−3 M mixture SDS:OMC-10=4:1. Such tailored enabled authors achieve 93–94% retention blue using hydrophilic made cellulose. could also be considered research method, helpful determining important parameters such as loading binding constant characterize solutions. Additionally distribution coefficient employed extraction studies can resolved.
