【摘要】 用热力学计算了InP-H₂-KBH₄体系中磷的组分与温度的关系,从理论上探讨了用气相色谱分析固相中磷的可能性。建立了不经化学预处理,用气相色谱直接测定固、液、气相样品中的磷及其磷化物的方法,测定结果与分光光度法基本一致。用逆向喷淋的方法对半导体工艺尾气中的磷进行了有效的治理。更多还原

【Abstract】 It is based on thermodynamic theories to calculate relationship between the concentration of phosphoric species and temperature. It is demonstrated possibility to analyse phosphorus in solid state by using gas chromatography. The method of determinating the concentration of phosphorus and phosphide in solid, liquid and gas state without pre-treat samples has been built and determination result is practically the same as spectrophotometer. There are very effective abatement results to tail gases is the fabricating of semiconductor process with counter-current spray system.更多还原
