Penggunaan Biopolimer Polikaprolakton Sebagai Matrik Herbisida Lepas Lambat Asam 2,4-Diklofenoksi Asetat
Abstrak: The study on 2,4-Dichlorophenoxyacetic acid
(2,4-D) microencapsulation by solvent evaporation method using polycaprolactone
(PCL) as a polimer has been done. The monitored of data how the effect release
of substance active toward coated during 480 minutes. From the result of
disolution gave rapid disolution of microcapsulation 2,4-D higher at formula 2
rather than formula 1 and 3. This show thickly upholstry of PCL have an effect
on to release of substance active. Kinetics method release of substance active
of microcapsule 2,4-D following order zero, first order and equation of
Higuchi.
