Selective separation of Bisphenol A from aqueous solution using supported ionic liquid membrane

Adsorption mechanism of magnetically separable Fe 3 O 4 /graphene oxide hybrids

“…In general, there were three possible mechanisms for the adsorption of BPA on carbon-based materials, including electrostatic interaction, hydrogen bonding and π-π attractions of aromatics [42]. However, the increase in the adsorption capacity of correlating with the dianion [43,44]. BPA maintained its molecular form at pH＜8.0 and was partially or fully deprotonated to monovalent or divalent anions at pH＞8.0 [3].…”

Facilitated transport of phenol through supported liquid membrane containing bis(2-ethylhexyl) sulfoxide (BESO) as the carrier

“…The SLM technique has been employed by several researchers for PhOH separation using various basic and solvation reagents, including different alkylamines (e.g., Amberlite LA-2 and trioctylamine [14]), phosphorous-based extractants (TBP [15], TOPO [16] and Cyanex 923 [17,18]), ionic liquid [19,20], and vegetable oils [21], as carriers in the membrane. Methyl isobutyl ketone (MIBK) has been used as a liquid membrane for removal of PhOH by SLMs [22].…”

Molecularly imprinted nanofiber membranes enhanced biodegradation of trace bisphenol A by Pseudomonas aeruginosa

“…It was reported that immobilized bacteria grew better than suspended ones [26]. In water samples containing Pb 2+ or Cd 2+ , the total amounts of bacteria in the positive and negative control groups were significantly lower than those in distilled water (Fig.…”

“…Moreover, BPA is in non-dissociated state in surface water and waste water because pH levels of these water samples are normally less than the pKa of BPA (pH = 9.7) [26]. Therefore, pH did not affect the selective adsorption of BPA by MIP.…”
