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.
