This research aimed to prepare and study the controlled release of agrochemical herbicide based on new nanocomposites, namely zinc layered hydroxide-3-(4- methoxyphenyl)propionate (ZLH-MPP) and layered double hydroxide-3-(4- methoxyphenyl)propionate (LDH-MPP). This research is divided into three parts which are synthesis of nanocomposites, characterization and controlled release. ZLHMPP nanocomposite was synthesized using direct reaction of an aqueous suspension of zinc oxide with MPP solution. Whereas, LDH-MPP nanocomposite was synthesized using an ion exchange method between nitrate ion and MPP anion. The physiochemical properties of ZLH-MPP and LDH-MPP nanocomposites were characterized using powder x-ray diffraction (PXRD), Fourier transform infrared spectroscopy (FTIR), carbon, hydrogen, nitrogen, oxygen and sulphur analysis (CHNO-S), inductive coupled plasma optical emission spectrometry (ICP-OES), thermogravimetric analysis and derivative thermogravimetry (TGA/DTG), and field emi.....

This  research  aimed  to  synthesis  active  agent-zinc  layered  hydroxide  intercalated agrochemical   nanocomposites   namely   zinc   layered   hydroxide-sodium   dodecyl  sulphate-isoprocarb    (ZLH-SDS-ISO),    zinc    layered    hydroxide-sodium    dodecyl  sulphate-propoxur  (ZLH-SDS-PRO)  and  zinc  layered  hydroxide-sodium  dodecyl  sulphate-thiacloprid  (ZLH-SDS-THI)  using  ion  exchange  method  for  pest  control. Surface  modification of nanocomposites was performed using chitosan and cellulose acetate.  The   nanocomposites  were  characterized  using  powder  x-ray  diffraction (PXRD),  Fourier  transform   infrared  (FTIR),  elemental  analysis,  thermogravimetric and  differential  thermogravimetric   analysis  (TGA/DTG),  field  emission  scanning electron  microscope  (FESEM),  and  surface  area   analysis.  The  results  of  PXRD patterns  showed  the  basal  spaci.....
