Removal and fate of 18 bisphenols in lab-scale algal bioreactors

The removal of 18 bisphenols at wastewater relevant concentrations (?g L ?1 range) was investigated and compared between Chlorella vulgaris cultures with pH adjusted to 6.8 non-adjusted where raised above 10. Bisphenols a high partition coefficient (log P > 6) partitioned biomass soon after spiking, whereas low < 4) remained largely in the aqueous phase. Hydrophobic BPF isomers were removed large degree conditions, while BPS BPAF most recalcitrant. overall average 13 days similar both experiments, 72 ± 2% 73 5% series, respectively. correlated chlorophyll concentration for meaning that algae played crucial role their removal, culture also governed some compounds. • Removal photobioreactors ranged from 25% 99%. Final compound log P. adjustment influenced 2,2?-BPF, BPA, BPC2, BPAF, BPC. After days, residual mainly present
