中文摘要:

      以2,4-D为代表的苯氧羧酸类除草剂, 低浓度为保花保果生长调节剂, 调节细胞生长及愈伤的分化、提高保鲜时间, 高浓度为除草剂, 该类除草剂难降解, 易污染地下水, 广泛、大量的应用会使植物产生畸形, 影响人体中枢神经系统, 具有潜在的致癌性和致突变性。因此, 快速、灵敏、准确地检测出苯氧羧酸类残留是保证农产品、环境安全的重要手段, 本文概述了苯氧羧酸类除草剂的前处理方法及不同检测方法在检测农产品、环境水样等样品中苯氧羧酸类除草剂残留的研究进展。综合对比了色谱法、联合技术、免疫法、纳米材料及传感器等检测方法在苯氧羧酸类检测中应用的优缺点, 提出了未来检测小分子物质的发展趋势。

英文摘要:

      Phenoxy carboxylic acid herbicides represented by 2,4-D as a growth regulator for flower and fruit conservation in low concentration, which can regulate cell growth and differentiation of callus and improve the fresh-keeping time. Phenoxy carboxylic acid herbicides are herbicides with high concentration , which are difficult to degrade and easy to pollute groundwater. Its extensive and extensive application will cause deformity of plants and affect the human central nervous system, which has potential carcinogenicity and mutagenicity. It is an important means to ensure the safety of agricultural products and environment that detecting phenoxy carboxylic acid herbicides residue in rapid, sensitive and accurate method. This paper summarized the research progress of pretreatment methods and different detection methods in detecting phenoxy carboxylic acid herbicides residues in agricultural products, environmental water samples and other samples, comprehensively compared the advantages and disadvantages of each method, and put forward the development trend of detection of small molecule substances in the future.
