The removal of tetracycline (TC) with nanoscale zerovalent iron modified by starch (starch-NZVI) was investigated using batch experiments as a function of reactant concentration, pH, time, competitive anions and ionic strength. The removal efficiency of 99% was obtained, 30% which was contributed from the adsorption and degradation and 69% which was attributed to flocculation when 500. mg/L TC was processed with 0.20. g/L starch-NZVI. The TC removal capacity of starch-NZVI increases with increasing the TC concentration. Furthermore, the floccul...
