四苯硼钾微波重量法测定硫酸钾、氯化钾中氧化钾的研究

Studies on the detetmination of K_2O in K_2SO_4 and KCl by using microwave gravimetric analysis method

研究建立了在样品处理过程中不使用甲醛并用G4玻璃坩埚过滤四苯硼钾沉淀,微波加热恒重,测定硫酸钾、氯化钾中氧化钾含量的方法。确定了微波功率300W,加热干燥恒重时间6min。方法省时、简便、实用、无毒害、符合生产要求。

The paper studied and set up a methad of determaining K20 in K2SO4 and KC1 by using C4 glass pot to filtrate four benzene boron potassium deposition and nficrowave heating to constant weightiness, but not using formaldehyde in the process, Through the experiment, some conditions were obstained that the microwave power was 300W, the time of heating and drying to constant weightiness was 6 minites. The method was time - saving, simple, utility and no poisonous harm, according with produce requirement.
