摘要
苦味酸钾溶于水后呈亮黄色,在可见光波长范围对光有一定的吸光度,而高氯酸钾的存在对吸光度不会产生不良影响。使用分光光度法测定共沉淀点火药中苦味酸钾的含量。研究苦味酸钾的浓度与吸光度的关系,并用于实际样品中苦味酸钾含量的测定。
potassium picrate is bright yellow when dissolved in water, and has a certain absorbance in the visible wavelength range, but the presence of potassium perchlorate has no adverse effect on the absorbance. The content of potassium picrate in co-precipitated igniter can be determined by spectrophotometry. The relationship between the concentration of potassium picrate and absorbance can be studied and applied to the determination of potassium picrate in practical samples.
