Absorbtion of of Mg and Pb

PH-sensitive Absorbent: Anionic Polyacryamide/Cassava Starch Hydrogels containing Natural Rubber for Lead and Magnesium removal from aqueous Solution

December 4. 2017 - The novel absorbent from polyacrylamide (PAM), cassava starch and natural rubber (NR) by microwave assistance were produced to remove lead ion and magnesium ion in aqueous solution. The absorption of Mg2+ and Pb2+ of the novel absorbent increases as function of sample weight due to high site group or carboxylic group of absorbent. The highest Mg2+ and Pb2+ absorption of absorbent was observed at base medium. When the contact time of absorbent for removing Mg2+ and Pb2+ increase, the degree of ion absorption raised also. The optimal condition of Pb2+ absorption for this absorbent was 20 h of contact time.
