| 摘 要： | 参照OECD301B标准,以降解过程中的二氧化碳生成量作为表征指标,研究了五种常用阻垢剂和两种新型阻垢剂的可生物降解性,得出了阻垢剂的可生物降解性数据、生物降解规律及聚合物分子结构与可生物降解性的关系。研究结果表明,增加聚羧酸阻垢剂分子结构中羧基的数目、酯基支链以及向主链中插入氮、氧元素,均可提高其可生物降解性,后两种方法特别有效。

| Abstract: | According to OECD 301B standard, the biodegradability of five common and two new types of scale inhibitor were studied by using the production of carbon dioxide (PCD) as a token. The data and rules of the biodegradability, and the relation between the molecular structure of polymer and the biodegradability were also obtained. Increasing the number of carboxyl group or ester branched chain, as well as inserting nitrogen or oxygen element into the backbone of the molecules of polycarboxylates could improve their biodegradability, and the latter was especially effective. |
