An efficient recovery technique of lignosulfonate from the wastewater is of necessity in order to meet the wastewater treatment requirement and as a source of valuable material that has wide range of industrial applications. Several technologies that have been used to separate lignosulfonate from the waste water are precipitation, ion-exchange process and electrolysis, which offer some advantages as well as drawbacks over others. Supported liquid membrane (SLM) is gaining worldwide importance for its use in the separation and recovery of various components as it offers advantages such as simultaneous extraction and stripping steps, low consumption of extractant and high selectivity. In this study, an attempt was made to extract lignosulfonate from its aqueous solution through a flat sheet supported liquid membrane using trioctylamine (TOA) as carrier. The important parameters governing the extraction process of lignosulfonate, which are types of support material, types of solvents, types of stripping agents, feed flow rate and feed phase pH were investigated. The process was conducted in a liquid membrane cell with continuous flow system. The results show that SLM system is selectively extracting lignosulfonate from the aqueous solution. The optimum lignosulfonate extraction was achieved at 37.5% by using TOA-Kerosene-PVDF membrane system, NaOH as stripping agent, 100 mL/min of feed flow rate and feed at pH 2. The experimental results also show that the SLM system is stable for more than 9 hours fahmimoksen UTM 91 p.
