On-line Determination of Formaldehyde In Tannery Effluent by Reverse Flow Injection Analysis
摘要
Abstract
In order to control the pollution of formaldehyde in tannery effluent,a fast,sensitive,and accurate reverse flow injection analysis spectrophotometric method was developed and presented.This method was based on the reaction of formaldehyde and phloroglucinol produced a redsubstance in alkaline environment.The absorbance of the substance was measured at 470nm,and then can detect qualiity of formaldehyde.Under the optional conditions,the linear range of this method was 10-2000 μg/L,and concentration and peak height had a good linear,the Linear equation was 0.0724x+ 4.8494(R2 =0.9994); the relative standard deviation is 0.27％ (n=10),the detection limit is 3 μg/L.This method has the advantage of little reagents,simple operation and high precision,it can be used to determination of formaldehyde as a viable in tannery effluent.关键词
