The article presents the effectiveness of phosphate sorption on the unmodified and modified (animation from the initial activation by epichlorohydrin) husks Arachis hypogaea. Studies performed determined dose activating agent (epichlorohydrin), adsorption capacity of unmodified and modified husks Arachis hypogaea, best among the tested adsorption pH as well as the equilibrium time. Langmuir model was used to describe the results. The highest removal efficiency of phosphorus compounds using unmodified husks Arachis hypogaea was obtained at pH 8, and with aminated at pH 5. The study of phosphate equilibrium concentration time obtained for both sorbents was carried out at three concentrations of 0,1; 0,5 and 1 mg/L. The highest sorption efficiency of the phosphate onto both sorbents was achieved after 60 minutes of the process. After the equilibrium time the effect of partial nutritient release was observed, which could be related to the change in pH of the solution by the sorbent. Studies have shown that the modification consists in the amination of husks Arachis hypogaea with pre-activated with epichlorohydrin increases their effectiveness removal of phosphorus compounds. The maximum adsorption capacity of unmodified husks with towards phosphate was 0.011 mg/g, while the husks animated with initial activation – 0.10 mg/g.
