AI Technical Summary
Technical Problem
Existing polyaluminum ferric chloride flocculants cannot effectively degrade organic molecules with stable C-Cl bond structures that exist in a dissolved state, thus affecting the overall removal efficiency of wastewater pollutants.
Method used
Cobalt ferrite was loaded onto the surface of nanoporous silica, and tartaric acid was grafted onto it via an amidation reaction to anchor aluminum-iron hydrolysate polymers, thus constructing composite particles with magnetic, catalytic, and specific adsorption functions.
Benefits of technology
It achieves synergistic removal and efficient separation of heavy metals, recalcitrant organic matter and conventional pollutants, improving wastewater treatment efficiency and avoiding inhibition of microbial activity.
