The dosages required for Cr(VI) removal are dependent upon the speciation of Cr(VI) with molar ratio between Aliquat 336 and Cr(VI) of 1:1 and 2.8:1 for HCrO4- and CrO24-, respectively. Efficiency of Cr(VI) regeneration is influenced by pH and chloride ion concentrations. Based on the affinity order of HCrO4- >

In the current study, CASX with a ceramic MF membrane integrated for separation of spent solvent was employed to remove and recover metal from wastewater. MF was operated either in crossflow mode or dead-end with intermittent flushing mode. Under crossflow mode, three distinct stages of flux vs. TMP (trans-membrane pressure) relationship were observed. In the first stage, f

Through pressurization of solvent with compressed air followed by releasing air-oversaturated solvent into metal-containing wastewater, MSAB were generated instantaneously. The enormous surface area of MSAB makes extraction process extremely fast and achieves very high aqueous/solvent weight ratio (A/S ratio). CASX process completely removed Cr(VI) from acidic electroplating wastewater under A/S ratio of 115 and extraction time of less than 10 s. When synthetic wastewater containing Cd(II) of 50 mg l(-1) was treated, A/S rat
