摘要
研究了粘土负载 K2 Fe O4缓释剂制备、水溶出特性和 Fe(OH) 3 对 Fe O2 -4水解反应的催化作用。考察了温度、总吸收量和存放时间等对缓释剂中 Fe O2 -4水溶出的影响。结果表明 ,该缓释剂能使 Fe O2 -4在水中缓慢溶出、浸出液稳定性高 ,制剂在水中长时间浸泡仍保持高强度。这些特性为 K2 Fe
The preparation and water dissolving behavior of K 2FeO 4 releasing agent and the catalytic behaviour of Fe(OH) 3 in the hydrolysis reactior of FeO 2- 4 were studied in this paper. The effects of temperature, primary absorbance and storage time on the property of dissolving out FeO^2- 4 from the releasin agent were examined. The results showed that the releasing agent could release FeO^2- 4 slowly in water and still kept high mechanical strength when soaked in water for a long period of time, and the leaching solution obtained had high stability. All these properties make it possible to apply the releasing agent to water treatment.
