用微波密封快速法测定CODCr并与国标回流法比较和进行抗干扰实验,结果表明:两种方法的线性相关系数r0.01,8>0.999,且微波密封快速测定法消解时间(0.25h)比国际法(2h)短。建议尽快将微波密封快速法纳入国家标准。 |

Abstract: |
The sealed elimination reaction with microwave(SERM) was used to detect chemical oxygen demand (CODCr) of polluted water,and compared with national standard reflux method and went through anti disturbing test.The result showed that the two methods had a high linear correlation coefficient (r0.01,8>0.999), and the eliminating time of SERM (0.25 h) was less than reflux method (2 h). It is suggested that the method should be accepted and involved in the national standard. |
Key words: microwave eliminate chemical oxygen demand (COD) |
