| 1 | Arsenic Removal from Pinctada martensii Enzymatic Hydrolysate by Using Zr(Ⅳ)-Loaded Chelating Resin显示文摘The present study investigated the removal of inorganic arsenic from Pinctada martensii enzymatic hydrolysate through unmodified resin(D296) and Zr(Ⅳ)-loaded chelating resin(Zr-D401).By loading Zr to macroporous chelating resin D401,the as exchange adsorption active sites are generated.This transforms D401 from a material that does not have the arsenic adsorption capacity into a material that has excellent arsenic exchange adsorption capacity.The static adsorption experiments were conducted to investigate the optimal removal condition for D296 and Zr-D401.The experimental results show that: the optimum condition for D296 is that T= 25℃,pH = 5,resin additive amount = 1 g(50 mL)-1,and contact time = 10 h,the corresponding arsenic removal rate being 65.7%,and protein loss being 2.33%;the optimum condition for Zr-D401 is that T=25℃,pH = 8,resin additive amount = 1 g(50 mL)-1,and contact time=10 h,the corresponding arsenic removal rate being 70.3%,and protein loss being 4.65%.These results show that both of the two resins are effective in arsenic removal for preserving useful substance.Our research provides scientific evidence and advances in the processing technology for heavy metal removal in shellfish. | YANG Xiaoman DAI Wenjin SUN Huili PAN Jianyu | 2013 | Journal of Ocean University of China2013，12，3： | 2 |
