Copper hydroxide nitrate/calcium silicate/graphitic carbon nitride nanocomposite material based absorbent for wastewater treatment

A method of absorption includes contacting a copper hydroxide nitrate/calcium silicate/graphite-phase carbon nitride [Cu 2 (OH) 3 NO 3 /CaSiO 3 @g-C 3 N 4 ] nanocomposite catalyst with a solution including one or more pollutants. Further, the method includes absorbing the one or more pollutants on the Cu 2 (OH) 3 NO 3 /CaSiO 3 @g-C 3 N 4 nanocomposite catalyst.

Claims preview

1 . A method of absorbing one or more pollutants in wastewater, comprising: contacting a Cu 2 (OH) 3 NO 3 /CaSiO 3 @g-C 3 N 4 nanocomposite-based absorbent with a solution comprising the one or more pollutants; thereby absorbing the one or more pollutants on the Cu 2 (OH) 3 NO 3 /CaSiO 3 @g-C 3 N 4 nanocomposite-based absorbent. 2 . The method of claim 1 , wherein the Cu 2 (OH) 3 NO 3 /CaSiO 3 @g-C 3 N 4 nanocomposite-based absorbent comprises: a graphite-phase carbon nitride (g-C 3 N 4 ) in an amount of 20 to 40 percent by weight (wt. %), a copper hydroxide nitrate (Cu 2 (OH) 3 NO 3 ) in an amount of 20 to 40 wt. %, and a calcium silicate (CaSiO 3 ) in an amount of 20 to 40 wt. %, based on a total weight of the Cu 2 (OH) 3 NO 3 /CaSiO 3 @g-C 3 N 4 nanocomposite-based absorbent. 3 . The method of claim 1 , wherein the one or more pollutants is an organic pollutant.
