15K are studied,and the medium effect of potassium tetraphenylborate in the mixed solvents of water ethanol is discussed.

１５Ｋ下，对四苯硼钾在不同比例的水－乙醇混合溶剂中的活度积及从水到混合溶剂中的迁移自由能进行了研究，并对其在水－乙醇混合溶剂中的介质效应进行了讨

When w(K2O)is under 10% in compound fertilizers(including inorganic or organic substance),atomic adsorption spectrometry is proved suitable for K2O determination,replacing the accepted standard tetraphenylboron sodium gravimetric method or flame photometry.

通过实验说明,当复混肥(含有机-无机及有机复混肥)中w(K2O)<10%时,可用较快速的原子吸收法代替目前标准中规定的四苯硼钾重量法或火焰光度计法测定钾含量;当复混肥中K2O含量较高时,仍宜用四苯硼钾重量法测定钾含量。
