摘要
介绍了绘制苯胺校准曲线时,用硫酸氢钾溶液替代固体硫酸氢钾或无水碳酸钠调节pH值的改进方法,结果表明这一改进不仅提高了方法精密度,而且操作简便。
Potassium hydroges sutfate solution supersedes the solid potassium dydrogen sulfate or anhydrous sodium carbonate to improve the method of adjusting pH in drawing aniline calilrtion curve. The results show that the improvement not only heightens the precision but also makes the operation easy.
