Synthesis, characterization and controlled release properties of magnesium aluminium layered double hydroxide 4-chlorophenoxyacetic acid nanocomposite / Nur Suhana Mohd Ali

Layered double hydroxide (LDH)-based nanohybrid, created by interacting LDH nanocomposite with another nanoparticles, are come out in active area for environmental protection, healthcare, and storage of drugs or herbicides. In this study, Herbicides, 4-chlorophenoxyacetic acid were intercalated into...

In this study, Herbicides, 4-chlorophenoxyacetic acid were intercalated into MgAl-layered double hydroxide (LDH) by using molar ratio 2 (R=2). It is synthesised via co-precipitation method at pH 10 (± 0.5). The intercalation compound (MgAl-4CPA), was characterised using PXRD and FTIR-ATR to confirm that guest anion are successfully intercalated into MgAl-LDH nanohybrids. The XRD pattern shows that at concentration 0.7 M, the basal spacing shift from 8.9 Å to 9.3 Å, which means the guest anion was successfully intercalated.

This study offered that controlled release of 4CPA from LDH can created safer agent of agrochemicals that can be used in agricultural fields.
