摘　　要：将氢氧化钾成品配成一定浓度的水溶液之后,在酸性条件下,用总有机碳测定仪测定其中碳酸盐的含量,测定所需时间短,需要的玻璃仪器和试剂药品比较少,人为因素对测定结果影响小,而且测定结果的准确度高,精确度好,因此,此方法可快速准确测定氢氧化钾产品中碳酸盐的含量。After the solution of potassium hydroxide was prepared with a certain concentration,the content of carbonate was determined by total organic carbon analyzer under acidic condition.The determination time is short,the glass instrument and reagent drugs are less needed,the human factors have little influence on the determination results,and the accuracy of the determination results is high and the accuracy is good.Therefore,this method can quickly and accurately determine the content of carbonate in potassium hydroxide products.
