摘要
采用正交设计优化法研究了硫酸+焦硫酸钾湿法熔融(化学法)分解碳氮化钛,以较少的实验次数确定了蒸馏分离和试样分解的最佳分析条件,通过条件实验,建立了相应的分析方法,测定结果与惰气熔融热导法一致。
The experimental conditions of the neutral titration method for determining the nitrogen content in (Ti(CN)) after wet process fusion in H_2SO_4+K_2S_2O_7 and distillation separation were investigated by orthogonal design optimization method, and the analytical method was developed. The determination results are consistent with those obtained by thermal conductivity method after fusion in inert gas.
