Elimination of orthophosphate from synthetic leachate using adsorption on bentonite clay

The composition of leachates is very variable and rich in toxic compounds, which requires treatment before discharge into the natural environment order to avoid their impact on and/or human health comply with requirements regulatory standards environment. Among parameters indicating pollution by leachates, we have COD, BOD5, conductivity, pH, presence ammonium ions, nitrite, nitrate, chloride, orthophosphate, etc. This study presents results synthetic leachate orthophosphate adsorption tests bentonite clays. For determination concentration leachate, after adsorption, applied method Ultra-Violet spectroscopy. capacity bentonite, amount needed removal efficiency were determined. yield reaches up 32.6 % for 5 g/L stirred 4 hours exceeds 39,19 24 stirring.
