Abstract
Novel redox-responsive hydrogels were prepared based on disulfide-crosslinked carboxymethyl cellulose for the controlled-release of agrochemicals. After release, the reduced hydrogels could capture heavy metal ions in soil via strong complexation between the ions and thiol groups generated by disconnected disulfide bonds, thus benefiting plant growth and soil remediation synchronously.
摘要
基于二硫键交联的羧甲基纤维素制备了新型氧化还原响应水凝胶，用于控制释放农用化学品。释放后，还原水凝胶可以通过断开的二硫键生成的巯基与离子之间的强络合作用，在土壤中捕获重金属离子，从而有利于植物生长和土壤修复同步进行。
