摘　　要：于分析试样中加入已知过量铜盐，经研磨浸溶使试料中金民铝与Ｃｕ２离子发生置换反应而析出等物质量的铜，剩余Ｃｕ２洗出后用电重量法测定并由铜量差值间接计算金属铝量，再由总铝量计算Ａｌ（Ⅲ）含量。Excessive copper salt is put in analysised sample.Aluminium in the sample raises a replacement reaction withCu2+ by grinding and immersing. A part of Cu2+ is replaced and the other part of Cu2+ can be determinated byelectrogravimetric method after it is washed out. Then the quantity of aluminium can be calculated indirectly by thedifference of copper quantity. Quantity of Al(Ⅱ)can be calculated by de+termination of total aluminium in the sample.
