| 4 | Biosorption of Cd from Aqueous Solution by Live and Dead Biomass of Fusarium oxysporum Isolated from the Sludge of Abandoned Mine显示文摘Owing to exploring the biosorption mechanism of Fusarium oxysporum to Cd,the adsorption capacities of live and dead biomass of F.oxysporum strain KF2 were detected.The result showed both the live and dead biomass of strain KF2 could tolerate the Cd concentration up to 200 mg/L,and had the largest adsorption capacities for Cd,at 2.21 and 1.86 mg/g,respectively,with the inoculation amount of 3 g,the pH at 6,and the initial Cd concentration of 100 mg/L.The pseudo-second-order kinetic model(live biomass r^(2)>0.99,dead biomass r^(2)>0.90)was more suitable for describing the adsorption process of strain KF2.It indicated that the physicochemical adsorption on the cell surface might be the main pattern for Cd removal.Furthermore,the FTIR results showed that the main functional groups for cell wall to bind Cd were carboxyl,hydroxyl,amino,and phosphate. | Chongju WANG Xiaolu YUAN Xuejiao JIA Jingtao FAN Yue LI Lin MEI Zuolin LIU | 2022 | Meteorological and Environmental Research2022，13，5： | 0 |
