安捷伦7890B-2M*1/4 玻璃柱测定水中六六六和滴滴涕的详细资料

玻璃柱测定水中六六六和滴滴涕
玻璃柱测定水中六六六和滴滴涕 详细信息：

六六六和滴滴涕均为有机氯农药,在水中的溶解度小,化学性质稳定,难以降解.目前虽已禁止使用此类农药,但仍有检出。

浩瀚色谱（山东）应用技术开发有限公司采用气相色谱电子捕获检测器对水环境中的六六六和滴滴涕进行分析.水样经过液液萃取浓缩后进样,使用1.5%OV-17+1.95%QF-1/Chromosorb AW DMCS（80-100目）玻璃柱,用外标法定量.结果表明:在所选择的色谱操作条件下,六六六和滴滴涕在0.0096～2.90 mg/L之间线性良好,相关系数大于0.9964,检出限为0.01～0.04 μg/L,水样加标回收率为93％～135％,相对标准偏差为2.4％～4.5％.

Determination of hexahexahexanol and DDT in water by glass column
Determination of hexahexahexanol and DDT in water by glass column Details:

666 and DDT are both organochlorine pesticides, with low solubility in water, stable chemical properties and difficult to degrade. Although the use of such pesticides has been banned, they are still detected.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. uses gas chromatography electron capture detector to analyze hexahexahexanol and DDT in water environment. QF-1/Chromosorb AW DMCS (80-100 mesh) glass column was used for quantification by external standard method. The results showed that under the selected chromatographic operating conditions, the linearity of hexahexahexanol and DDT was good between 0.0096 and 2.90 mg/L. , the correlation coefficient was greater than 0.9964, the detection limit was 0.01-0.04 μg/L, the recovery rate of water samples was 93%-135%, and the relative standard deviation was 2.4%-4.5%.
