In vitro Adsorption of Paraquat onto Substituted Chitosan Beads.

Abstract: Paraquat removal by chitosan with different substituents was investigated in vitro for evaluation of chitosan as a paraquat adsorbent in emergency treatment for acute Paraquat poisoning. Chitosan CM and SU, in which the hydroxyl group at the C6 position is replaced by a carboxymethyl and sulfonic group, respectively, removed paraquat abundantly in purified water. However an inhibitory effect of sodium chloride on Paraquat removal by CM and SU was recognized. On the other hand, paraquat removal by cross-linked … Show more

“…Therefore, further investigations are necessary to apply BS1000 for the removal of herbicides from the aqueous phase. The comparison of paraquat and diquat adsorption capability of tested bio-adsorbent including BS, BS1000, and other reported adsorbents is shown in Table 2 (Duman et al, 2019;Kamga, 2019;Liang et al, 2021;Martins et al, 2015;Nakamura et al, 1993Nakamura et al, , 2000Pavlovic et al, 2014). Regarding paraquat, the adsorption capability using BS1000 (28.7 mg g À1 ) was similar to or greater than that using other reported adsorbents (7.5-30 mg g À1 ).…”
