INVESTIGATION OF ADSORPTION CAPACITY OF NH4+, Mn(II), PHOSPHATE BY NANO-SIZED MnO2 ON PYROLUZITE.

Abstract

     Mangan dioxide is one of the transition metal oxides and is widely applied due to to its many important chemical and physical characteristics such as electrochemical, adsorption, oxygen catalyst. In this article, we will introduce some results on the study of MnO2 adsorption ability with NH4+, Mn(II), PO43- in nanometer sized on pyrolusite. Maximum absorption capacity is calculated by the Langmuir isotherm. Maximum absorption capacity of materials to NH4+, Mn(II), PO43- are 18,18 mg/g; 38,46 mg/g and 47,62 mg/g, respectively. 

Keywords. Mangan dioxide, ammonia, mangan, phosphate, nano-sized, material, pyrolusite.
