摘　　要：高品质片状氢氧化钾中硅酸盐、铁、钠、铝、钙、镍6项指标通常分别采用目视比色法、分光光度法、原子吸收法测定,其操作繁琐并且耗费时间较长。采用电感耦合等离子发射光谱仪可同时测定硅酸盐、铁、钠、铝、钙、镍6项指标。该法简便、快速,并有较高的精密度和准确度。Silicate, iron, sodium, aluminum, calcium, and nickel in high-quality flaky potassium hydroxide were respectively detected with visual colorimetry, spectrophotometry, and atomic absorption spectrometry.These methods are too complex and need too much time.Now the six elements （silicate, iron, sodium, aluminum, calcium, and nickel） can be detected at the same time with inductively coupled plasma spectrometry.The method is simple and rapid, and has a high precision and accuracy.
