海洋资源的化学XX盐化工废弃物高低温盐有效利用的研究

CHEMISTRY OF MARINE RESOURCES—XX STUDIES ON EFFECTIVE UTILIZATION OF HIGH AND LOW TEMPERATURE SALT DISCARDED MATERIALS FROM SALT CHEMICAL INDUSTRY

报道利用盐化工废弃物高低温盐制取无机阻燃剂氢氧化镁和具有广泛用途的氟硅酸钠的几种新方法。本文采用沉淀法，使高低温盐中的Ｍｇ２＋、Ｎａ＋得以有效的利用，其利用率可达１００％

Several new methods are reported in this paper. The magnesium hydroxide (inorganic flame retardant), sodium fluosilicate are prepared from high and low temperature salt (discarded materials from the salt chemical industry). The experimental results show that the precipitating method is the best method, making Mg ++ ,Na + in high and low temperature salt be effectively utilized. The rates of utiliztion are 100%.
