Controlled release of agrochemicals and heavy metal ion capture dual-functional redox-responsive hydrogel for soil remediation†
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.
