Nitrate is a stable and highly soluble ion with a low potential for precipitation or adsorption; nitrate is seldom present in geological formations; therefore, contamination due to nitrate is mainly attributed to anthropogenic sources.
Water resource pollution by nitrate occurs for many reasons and has effects on human health and the environment; therefore, nitrate removal from drinking water is necessary.
In this study, nitrate removal was attempted by the addition of sodium thiosulfate, and a 72% reduction in nitrate level was detected when 1 ml of a 1.09% solution of sodium thiosulfate was added to 100 ml of polluted water after 30 minutes of contact. The literature was reviewed to determine the effect of sodium thiosulfate on human health.
