城市垃圾堆肥有机碳测定方法的比较

Comparison of determination methods of organic carbon in urban waste compost

目的：探讨垃圾堆肥中混杂的未烧尽的煤炭对有机碳测定造成的干扰。方法：采用经典的K2Cr2O7容量法和稀释热法对垃圾堆肥有机碳进行了比较测定。结果和结论：稀释热法可减少垃圾中的煤炭对分析结果的影响。

Some unburned coal mingled with waste compost interferes with the determination of organic carbon. By using capacity method of classical K2Cr2O7 and method of dilution heat,Organic carbon in urhan waste compost is detertrined. Compared with deterwination results of two methods,it is shows that dilution heat method can reduce influence of analysis result causingly unburned coal in waste compost.
