Preparation of Sodium Carboxymethly Cellulose Hydrogels for Controlled Release of Copper Micronutrient
Abstract
In
this study, a series of nanoporous
sodium carboxymethyl cellulose (NaCMC) hydrogels were synthesized using FeCl3
ionic-crosslinker by changing the amounts of the components. Hydrogel formation percentages of the samples were determined and the
highest value was obtained as 96% for the hydrogel containing the most amounts
of polymer and crosslinker. Swelling/degradation behaviors of the hydrogels
were studied by changing time, temperature and pH and it was determined that
the swelling percentages regularly
decreased with increasing the amounts of polymer and crossliker. S%
values were determined to be 102% for the least swollen hydrogel. In general, NaCMC hydrogels
much more swelled in basic medium than acidic medium. Releasing of copper micronutrient from NaCMC
hydrogels were investigated by Atomic Absorption Spectrometer
measurements. Kinetic in vitro release
parameters, the release rate factor K and
the release exponent n of
micronutrients in hydrogel system were calculated. It can be concluded that the
produced hydrogel system having controllable release values is useful for
agricultural applications.
