摘　　要：采用 H.P.T.A.作显色剂 ,分光光度法直接测定 Na2 O- B2 O3 - Si O2 系统多孔玻璃制备酸浸析液中微量的硼 ,对其测定条件及干扰元素进行了详细的研究 ,确定了最佳测定条件。该方法不仅灵敏度及选择性都较好 ,而且精密度高 。Using H.P.T.A. as colour reagent, a spectrophotometric method for direct determination of microboron leached from porous glass in its preparation was raised. The conditions and interfering ions for the determination were investigated in detail. The optimum conditions were established. The sensitivity, selectivity and precision were good. The results were satisfied.
