| 摘 要： | 以棕壤、褐土和红壤为研究对象,比较了不同浸提方法,不同浸提剂对土壤中土霉素的浸提效率.结果表明,在所用的3种方法中,采用振荡浸提方法,以及Na2EDTA-McIlvaine缓冲液对土霉素具有稳定、高效的浸提回收率.土霉素形态初步分析连续浸提步骤为:以H2O、0.1mol/L CaCl2、和Na2EDTA-McIlvaine缓冲液为浸提剂依次浸提可分别得到水溶态、可交换态、吸附态和固定态土霉素.3种土壤中土霉素形态呈现吸附态>可交换态>水溶态的规律.

| Abstract: | Recoveries of oxytetracycline extracted were discussed with different extractants and extraction processes in the brown,cinnamon,and red soil.Stable and efficient extracted recovery could be achieved by using Na2EDTA-McIlvaine as a extractant in the shake flask extraction.In addition,a sequential extraction procedure was developed to study the chemical speciation of oxytetracycline in the soils.The soils were extracted by H2O,0.1mol/L CaCl2,and Na2EDTA-McIlvaine in order.As a result,water-soluble,exchangeab... |
