Synthesis of Humic Acid Adsorption Resin

The humic acid resins with adsorption characteristics are synthesized using crosslinking agent phenolic-formaldehyde resin and humic acids.Curing temperature,curing meaning,content of phenolic-formaldehyde resin are investigated.The results show that the capability of synthesized resin to Cu(Ⅱ) is 15.04 mg/g under optimal reaction conditions: hydrochloric acid catalyst,double content of phenolic-formaldehyde resin relativing to sodium humic acid,300℃curing temperature and 10 minute curing time.
