民用建筑工程室内空气中甲醛和氨的测定

Determination of Formaldehyde and Ammonia in Indoor Air of Civil Building Engineering

使用大型气泡吸收管采样,分光光度法定量测定民用建筑工程室内环境空气中的甲醛和氨。在本方法条件下,甲醛和氨标准曲线线性良好,相关系数(r)均在0.9996~0.9999。该方法在民用建筑工程室内空气中甲醛和氨的检测中操作简单,准确度高,重复性好,应用效果良好。

Formaldehyde and ammonia in indoor air of civil building engineering of using large bubble absorption tube samplingwere quantitatively determined by spectrophotometry.Under the condition of this method,the standard curves of formaldehyde and ammonia had good linearity,and the correlation coefficients(r)were between 0.9996 and 0.9999.The method was simple,accurate,reproducible and effective in the detection of formaldehyde and ammonia in indoor air of civil building engineering.
