本文提出了应用饱和硼酸抑制氟硼酸根(BF_4~-)水解,扣除Sn~(+2)离子干扰的新方法。当终点pH为2.51,其结果可按下式计算:当终点pH为3.85,其结果可按下式计算: G_(HBF_4)(mg/mL)=(NV_2/V—G_(Sn)/(1/2M_(Sn))×M_(HBF_4)
In this paper, a new method of using saturated boric acid to inhibit the hydrolysis of fluoborate (BF 4 -) and deduct the interference of Sn 2+ ions has been proposed. When the endpoint pH is 2.51, the result can be calculated as follows: When the endpoint pH is 3.85, the result can be calculated as follows: G_ (HBF_4) (mg / mL) = (NV_2 / V_G_ (Sn) / / 2M_ (Sn)) × M_ (HBF_4)
