Abstract: A nascent manganese oxide was used as adsorbent to deeply remove trace molybdenum from manganese sulfate solution.The effects of reaction time，concentration of MnSO↓4 solution，initial pH，reaction temperature and adsorbent dosage of nascent manganese oxide on adsorption of molybdenum in MnSO↓4 solution with nascent manganese oxide were studied.The results showed，the mass fraction of remainder molybdenum in manganese sulfate solution was less than 0.015 mg/L after molybdenum removing under the conditions of initial pH=1.0～3.0，30 min of adsorption time，80 ℃ of reaction temperature，20 g/L of manganese oxide in nascent manganese oxide suspension and more than 13.5 mL/L of adsorbent dosage.The molybdenum concentration in the solution had totally reached the requirement of special electrolytic manganese dioxide used for the production of mercury-free alkaline zinc-manganese batteries.The contrast results indicated that the molybdenum removing effect of nascent manganese oxide is far better than that of powder manganese oxide.
