等离子光谱法测定硅肥中有效硅含量

摘要

The article extracts the available silicon from silicon fertilizer by using diluted hydrochloric acid of 0 .5 mol/L and tests the content of the available silicon based on ICP -AES method .The method has the ad‐vantages of simple treatment and fast analysis ,w hich can meet the requirement of the determination of avail‐able silicon in silicon fertilizer .The experiment indicates that the method's result is in accordance with the traditional one and it is more simple and faster .%采用0．5mol／L稀盐酸浸提硅肥中有效硅，用等离子光谱法（ICP－AES法）测定了有效硅的含量，指出了该方法具有样品处理简单，分析速度快等优点，可以满足硅肥中有效硅测定需要。实验结果表明该法测定硅肥中有效硅与用传统方法测定结果基本一致。
