摘要
采用CO2生成量法(GB/T 20778—2006)对笔者之前报道过的两种无磷缓蚀阻垢剂聚天冬氨酸(PASP)复配物和聚环氧琥珀酸(PESA)复配物的生物降解性能进行了评价.结果表明,聚天冬氨酸复配物和聚环氧琥珀酸复配物28d的生物降解率分别达到了77.6%和76.8%,属于易降解类环境友好型缓蚀阻垢剂.
The biodegradability of two non-phosphorus corrosion and scale inhibitors,polyaspartic acid（PASP） composite and polyepoxysuccinic acid（PESA）composite,which were previously reported by the authors,are evaluated further by production of carbon dioxide test. The results show that the PASP composite and PESA composite both have excellent biodegradability and their biodegradation rates after 28 days reaches 77.6%and 76.8%,respectively. The two water treatment agents are easily degradable and environment-friendly corrosion and scale inhibitors .
