The guar gum-polyethylene glycol (GG-PEG) and cellulose acetate-polyethylene glycol (CA-PEG) hydrogel beads have
been synthesized using crosslinking agent polyethylene glycol with drop cast method. The newly fabricated beads have been
characterized by FTIR, FESEM, TGA and swelling studies. Water retention, water holding, and soil porosity tests have been
conducted on both hydrogel beads. The results showed that the swelling ratios for GG-PEG and CA-PEG were 350 g/g and
250 g/g, respectively. At high pressures, GG-PEG retained 20% more water than untreated soil, whereas CA-PEG retained
17.5%. The soil's water-holding capacity improved to 16.05% when treated with GG-PEG, compared to 9.69% with CA-PEG.
The porosity of soil increased to 69.45% in the case of GG-PEG hydrogel beads and 65.17% in the case of CA-PEG when
compared to untreated soil. The biodegradable studies of the hydrogel beads showed that GG-PEG was more susceptible to
degradability since it was a natural polymer. As a result, GG-PEG is more efficient than CA-PEG, and this study demonstrates
how natural polymers may be employed as superabsorbents to improve soil qualities by serving as conditioners.
