tetraphenylboron

1.The tetraphenylboron sodium gravimetric method must be employed when K2O is higher in compound fertilizer for enough accuracy.

当复混肥中K2O含较高时,仍宜用四苯硼钾重法定钾含。

2.METHODS Sodium tetraphenylboron gravimetric analysis was replaced by highly-accurate nephelometric titrimetry to determine potassium chloride in Compound sodium chloride injection.

方法用高精度散射度滴定法代替四苯硼钠重法。
