A solubility study was performed on both the chitosan and
CS–ZnONPs beads. The beads were tested with regard to their
solubility in each of 5% (v/v) acetic acid, distilled water and
0.1 M NaOH solution. A value of 1.0 g of each of the beads,
using analytical balance, was weighted accurately. The samples
were kept in each solution for about 24 h at room temperature
under stirring using mechanical stirrer (100 rpm). After that,
the mixture was filtered, washed with distilled water and dried
for 24 h at room temperature. Then, the dried samples were
weighted using the analytical balance.
