| Abstract: | 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. |
