Experimental investigation of the determination of volatile phenols and total cyanide in water by continuous flow analysis
Volatile phenols and total cyanide stand as pivotal parameters in water quality assessment and environmental conservation,playing a critical role in accurate water quality evaluation and environmental impact analysis.The contemporary landscape of detection methodologies in the industry is dominated by the prevalent use of online pre-treatment flow injection analysis and continuous flow analysis.However,a notable gap persists in China's regulatory framework,with the absence of a national and industry standard for the continuous flow-spectrophotometric method applied to cyanide detection in water(excluding drinking water).This absence poses significant challenges to the precise monitoring of cyanide in water samples.This research systematically explored the influence of factors such as reagent pH and concentration on detection outcomes through a controlled variable approach,successfully identifying optimal detection conditions.The test results of this method show a complete linear correlation.with detection limits reaching an impressive low of 0.279 μg/L for volatile phenols and 0.118 μg/L for total cyanide.Additionally,recovery rates from spiked experiments consistently fell within the range of 95.0%to 105%.Beyond providing invaluable insights and a foundational framework for the formulation of national and industry standards in water quality for volatile phenols and cyanide,this study introduces an environmentally conscientious methodology to the domain of water quality monitoring.
