This study aims to test the capacity of raw and chemically activated clays with sulfuric acid (H 2 SO 4) from three quarries in Tanout township of Zinder region (Niger) in the elimination of nitrite ions (NO 2). The methodology is based on tests with synthetic waters containing (NO 2) ions by varying certain parameters (contact time, pH, mass, concentration and temperature). The results obtained show that raw and activated clays adsorb (NO 2) ions well with more affinity towards activated clays. Removal capacities increase with contact time and concentration for some clays, but decrease with temperature, mass and sometimes pH. These results also show that these clays ofTanout are potential materials that can be used in the denitrification of natural waters in Zinder region.
