| Abstract: | The adsorption effect of potassium permanganate on chitosan was explored.The effects of pH,time and temperature on the adsorption was discussed.The comparative ideal adsorption product was got,IR-spectrum and UV-vis spectrum on the product are provided,at the same time it is confirmed that it is existing coordination bond between the chitosan and manganese.And pH value between 3 and 5,the absorption effect of the chitosan to manganese is better.The absorption is nearly equilibrium when the reaction time achieves over 52 hours,and higher temperature is advantageous to absorption. |
