In aqueous solution, the cellulose-based magnetic polyamidoxime adsolbent treated with hydrochloric acid (AMAO) was used for KMnO4 uptake. The probability of redox reaction was found to be very little. However, the alkali-treated adsor-bent (BMAO) reduces the Mn(Ⅶ) to Mn(Ⅳ) and the conversions ale mostly over 10%. The yidds of Mn(Ⅱ) or Mn(Ⅳ) are independent of the adsorption time.the initial concentration of potassium permanganate solution and the amount of the adsorbents used.The adsorption capacity of KMnO4 by BMAO is about 5-fold to the amount of the amidoxime groups in the adsorbent. The phenomenon of superequivalent adsorption is a reflection of physical adsorption.
