摘要:
选择市售次氯酸钠（NaClO）溶液，利用湿法制备高铁酸钾（K2FeO4），考察制备过程中反应时间、NaClO浓度、NaClO与三价铁［Fe（Ⅲ）］的投加比例（物质的量之比）、碱液种类和提纯方法等因素对K2FeO4制备纯度的影响，并对自制K2FeO4的稳定性和效能进行了分析。结果表明，选用的市售有效氯为6%~14%的NaClO溶液，当NaClO与Fe（Ⅲ）物质的量之比为5.0∶1时，制备的K2FeO4纯度高达98.43%。以氢氧化钾为反应碱液，制备的K2FeO4纯度更高且无需进行重结晶，流程更加简化且增强了废液的重复利用性。采用乙醇为前期清洗剂，借助超声技术进行K2FeO4粗产品提纯，优化了反应工艺，节省了成本。
Abstract:
Commercially available sodium hypochlorite (NaClO) solution was employed, and potassium ferrate (K2FeO4) was synthesized via the wet oxidation method. The effects of various parameters including reaction time, NaClO concentration, the molar ratio of NaClO to trivalent iron [Fe(Ⅲ)], the type of alkaline solution, and the purification method on the purity of the synthesized K2FeO4 were systematically investigated. Additionally, the stability and performance of the prepared K2FeO4 were evaluated. When the molar ratio of the commercial NaClO solution containing 6% to 14% effective chlorine to Fe(Ⅲ) was maintained at 5.0∶1, the resulting K2FeO4 product achieved a purity of up to 98.43%. The use of potassium hydroxide as the alkaline reaction medium enabled the preparation of K2FeO4 with higher purity, eliminating the need for recrystallization. This approach simplified the synthesis process and enhanced the reusability of the waste solution. Ethanol was employed as the initial cleaning agent, and ultrasonic technology was utilized to purify the crude K2FeO4 product, thereby optimizing the reaction process and reducing costs.
