Study on rapid determination of trace volatile phenol concentrations in water samples
摘要
Abstract
A high-speed analysis method for determination of trace volatile phenol concentrations in water samples using long optical length cuvette-flow injection was developed in this study.The detection limit of this method was 0.232 μg· L-1,the relative standard deviation was less than 0.553 μ g · L-1,the relative error was less than 0.185％,and the spiked recoveries were between 91.0％～99.8％.The calibration curve of volatile phenols show good linearity (r=0.999 9).Compared with traditional national standard method (Water quality-Determination of volatile phenolic compounds-4-AAP spectrophotometric method,HJ503-2009),the determination deviation was 2.59％～8.25％.This developed method could analyze 24 water samples per hour,but the traditional method could only analyze 5 samples per hour.These results implied that our developed method could apply to analysis volatile phenol in amount water samples for rapid and accurate determination,especially suitable for emergency monitoring of the accident.关键词
