Adsorbtion of Amantadine Hydrochloride Wastewater: The Choice of Adsorbent

Treatment of the wastewater containing amantadine hydrochloride with adsorption in order to achieve lower the effluent COD of amantadine hydrochloride. A comparison of the adsorbents (activated carbon, diatomite, zeolite, slag and steel slag, etc.) on amantadine hydrochloride water the maximum saturation capacity and adsorption isotherms, and the factor of economic, to finalize a kind of the adsorbents that is the high effect and the economy. The results showed that: With the adsorption to treatment the wastewater treatment with amantadine hydrochloride is effective. Maximum adsorption capacity of activated carbon was 8.758mg / L, diatomite was 4.272mg / L, zeolite was 2.799mg / L, steel slag was 1.351mg / L, slag was 1.311mg / L. The adsorption isotherms of Activated carbon, diatomite, zeolite are more in line with the Freundlich model, the difficult degree to absorb the amantadine hydrochloride as activated carbon > diatomite> zeolite. In combination with other factors and economic factors, select diatomite as the best adsorbent at last.
