Scope

Scope: This document specifies a high-performance liquid chromatography method for the determination of organic acids (formic acid, acetic acid, propionic acid, and acrylic acid) in soil. This document is applicable to the determination of formic acid, acetic acid, propionic acid, and acrylic acid in soil. When the sampling quantity is 10g and the volume of the extract is 50mL, the method detection limit for formic acid is 20mg/kg, and the detection limits for acetic acid and propionic acid are 30mg/kg, and for acrylic acid are 0.2mg/kg. Main technical content: Formic acid, acetic acid, propionic acid, and acrylic acid are organic acids that are irritating and corrosive. They are important fine chemical intermediates and are widely used in pesticide, pharmaceutical, leather, and other industrial production. During chemical production processes, leaks, drips, and spills, as well as the discharge of three wastes (wastewater, waste gas, and waste residue), can cause organic acids to remain in the atmosphere, water, and soil. Acrylic acid can cause skin burns and may damage lung, liver, and kidney functions, with irreversible effects on human and other organisms' health and reproduction. It is listed on the World Health Organization's International Agency for Research on Cancer's list of Category 3 carcinogens. This document specifies a high-performance liquid chromatography method for the determination of organic acids (formic acid, acetic acid, propionic acid, and acrylic acid) in soil. It includes method principles, instrumentation, reagents or materials, samples, detection steps, quality control, and other content. It establishes a method of using pure water to shake-extract organic acids from soil and determine them by high-performance liquid chromatography. This method has the advantages of a wide application range, fast detection speed, and accurate and reliable test results, and is suitable for batch detection of organic acids in soil. It is innovative and its r
