Study of arsenic removal with ionic exchange resins in drinking water from Zimapan, Hidalgo State, Mexico

Anionic exchange resins were research with respect its capacity for removal arsenic content in water. Water of well V from Zimapan Hidalgo Mexico was used to make this research, because this water have a mean concentration of 480 +/- 11 mu g(.)L(-1) of arsenic and it is available as drinking water. The exchange resins employed were two strong anionic, one macroreticular (LRA-900) and other gel type (IRA-400), as soon as one third anionic weak macroreticular type (IRA-96). The experiments carried with this resins showing that IRA-900 has highest efficient in the process of arsenic removal from drinking water, because, it showed a treatment capacity of 700 (VaguaVres-1)-V-.; while that capacities of IRA-400 e IRA-96 resins were 320 and 52 (VaguaVres-1)-V-. respectively. The mean concentration of arsenic residue in the treatise water was 24 mu g(.)l(-1) and it is within the maximum level permissible by Mexican official norm for drinking water.
