复合高铁酸盐片剂的制备研究

Preparation of the Compound Ferrate Tablets

用浓碱水溶液中次卤酸盐氧化法制备出黏糊状的高铁酸盐,加入粘土、无水硫酸钠与高铁酸盐制成不同比例的复合高铁酸盐,并对其溶出的高铁酸根浓度进行测定.探讨了黏土、无水硫酸钠的加入量及加入顺序对复合高铁酸盐稳定性的影响,找到了制备复合高铁酸盐片剂的最佳条件,在此条件下制备的复合高铁酸盐片剂具有较高的稳定性,研究结果极具工业应用前景.

The potassium ferrate are prepared by the wet method of hypochlorite oxidation,and the compound ferrate are prepared by adding different proportions clay and sodium sulphate,it＇s concentration is determined.The factors of affecting stability of ferrate,such as clays the added quantity of the sodium sulphate and the sequence are studied,and the best condition of preparing compound ferrate has been decided.The compound ferrate tablet under the best condition has high stability.The result has great potential applications.
