苦味酸即三硝基苯酚,有毒有酚味,广泛用于制造有机玻璃、电池、制革、染料等化工工业,随工业发展,水中苦味酸的排放量也不断增加,以致造成水源的污染。 水中苦味酸的测定一般用于比浊法,灵敏度低,难以测出水源水中的含量,本文用气相色谱法,具有简 Picric acid, which is trinitrophenol, is toxic and has phenolic odor. It is widely used in the chemical industry such as plexiglass, battery, leather and dye. With the industrial development, the picric acid in water also increases continuously, resulting in the pollution of water source. Determination of picric acid in water is generally used for turbidimetry, low sensitivity, it is difficult to measure the water content of water, this paper by gas chromatography, with Jane
