Sorption behavior of methylene blue from aqueous solution by raphia fibers. Zhang, J.; Zhang, Y.; Lei, Y.; Pan, C. Photocatalytic and degradation mechanisms of anatase TiO. When the ratio (m/v) increases, at constant concentration of the dye, the adsorption capacity of adsorbent available is not fully utilized at a higher adsorbent dosage in comparison to lower adsorbent dosage. All the above-mentioned features render PLLA/PANI and PAN/PANI promising membranes for water treatment. Wang, D. et al. Wang, W.; Lin, F.; Yan, B.; Cheng, Z.; Chen, G.; Kuang, M.; Yang, C.; Hou, L.
