摘要
报道了一种用铬天青S直接比色法快速测定硅铁中铝的新方法,着重对分析样品的分解及酸度控制进行了条件试验,对各种试剂的用量进行了验证。结果表明:用铬天青S直接比色测定硅铁中的铝方法快速、准确、稳定,完全可以弥补容量法的不足,是一种实用性很强的分析方法。
It is a new method that determined aluminiun in siliconensen by chrome azurol S and spectro-photometric. We emphasized the condition experimentation of analyzed sample including decomposition and acidity controlling. At the same time we validated the dosage of all kinds of reagents. The results indicated: using CAS and spectrophotometric determined aluminium in siliconensen is a quick, veracious, stabilization. It can make up the shortage of volumetric method. It is a analysis method of high practicability.
