Animal blood meal protein containing more than 80%, the protein thiol and carboxyl group with strong ion binding capacity, especially the sulfhydryl binding force is extremely strong, can be combined with low concentration of inorganic ions. Study on Cr6+ in wastewater based on the passivation effect, the results show that the initial concentration of heavy metal ions on blood meal solution of Cr6+20mg/L has certain adsorption effect, adsorption after 18h, with the increasing of the amount of blood meal, blood meal on the adsorption capacity of Cr6+ and the removal rate increases linearly in the blood meal when adding 10 g, the adsorption amount of blood meal on Cr6+ and the maximum removal rate, and its value is 3.21 mg/g and 74.47% respectively. This study provides an alternative new technology for the removal of Cr6+ from wastewater.
