摘要
试样经掩蔽铁杂质后,在微酸性条件下用四苯硼钠沉淀钾离子再与钾标准进行比浊,该方法便捷,测定范围为≥0.4≤1.2g/l KC lO3。
After Iron impurity masked, potassium ions were precipitated with sodium tetraphenylboron in a weak acid condition. The resulting turbidity was compared with the potassium turbidity standard. This method is convenient and the testing range is 0. 4 - 1.2g/L KClO3.
