Commercial chitosan biopolymer has been used for heavy metal adsorption treatment at the Rmoch6 monitoring point of the Moche River. This alternative approach uses crustacean shell waste, abundant in the region of Sechura, Piura in Peru. Chitosan becomes a biodegradable raw material that removes heavy metals from the water of the Moche River, used for agriculture and animal consumption, preventing them from causing direct or indirect damage to our organism. In the research, the capacity of a commercial chitosan biopolymer to remove heavy metals from the Moche River was analyzed. The results showed that the concentrations of metals and water quality parameters exceeded the standards, but treatment with chitosan reduced the concentrations of heavy metals. The amount of chitosan and the optimum contact time for the removal of aluminum, arsenic, cadmium, cobalt, copper, iron, lead and zinc were determined by the test. In addition, it was found that natural zeolite and Gis-NaP have better arsenic and lead removal, while nano bentonite is better in iron and zinc removal. |
