摘要
本文报导了一种能够去除水中高浓度ＳＯ２－４的高效净水剂。它以廉价的铝土矿为原料，辅以适当添加剂，经简单处理，在７００℃～８００℃的温度下灼烧了３ｈ即可制成。将该净水剂投入含ＳＯ２－４（２２４８ｍｇ／Ｌ）水中，处理３０ｍｉｎ，就能达到国家饮用水标准。
Teh paper reports a water purifying agent to remove high concentration SO_4~2- in water. The agent was prepared from the cheap material bauxite and an adequate additive under the condition of burning at 700℃-800℃ for about 3h. When the agent is put into the water with high concentration SO_4~2- (2248mg/L) and treated for 30min the water can reach the national drinking water standards.
