苛化麸皮中甲基汞生成量的影响因素研究
THE EFFECT ON THE AMOUNT OF PRODUCED METHYLMERCURY IN THE CAUSTIC WHEAT BRAN FLOCCULANT
【摘要】 氯碱工业中,盐水精制所使用的苛化麸皮絮凝剂,与汞离子作用产生甲基汞。汞浓度增加温度升高,生成量明显增加。培养时间和溶液的pH均对生成量有明显影响。麸皮的水解和氧化是甲基汞生成的直接原因。
【Abstract】 Methylmercury can be formed in the brine system of the mercurycell of the chloro-alkali plants using caustic wheat bran as flocculant. Its formation relates with the concentration oi Hg (Ⅱ) , temperature, pH, and duration of the caustic process. Hydrolysis and oxidation of the flocculant is the direct cause for the formation of methylmercury.
