为了比较差减法和直接法对水中总有机碳测定结果,分别配制差减法和直接法的工作曲线,并分别通过差减法和直接法对不同水体中的总有机碳含量进行测定。比较测定结果,发现差减法和直接法对较清洁水体样品的TOC测定结果误差不大,而对废水样品的TOC测定结果误差较大。
為瞭比較差減法和直接法對水中總有機碳測定結果,分彆配製差減法和直接法的工作麯線,併分彆通過差減法和直接法對不同水體中的總有機碳含量進行測定。比較測定結果,髮現差減法和直接法對較清潔水體樣品的TOC測定結果誤差不大,而對廢水樣品的TOC測定結果誤差較大。

To compare the difference subtraction and direct method for total organic carbon in water measurement results, subtraction and direct method of working curve were prepare, and total organic carbon content of different water bodies were measured by subtraction and direct method. Compares the measured results, found by subtraction and the direct method for determination of the results, cleaner water samples TOC had rarely error, TOC determination of wastewater samples had big error.
