Application of Reclaimed Sodium Polyacrylate to Increase Soil Water Retention
The aim of this study is to investigate the impacts of salt denseness, temperature, and pH on swelling capability and the water retention capability in loam soil treated by reclaimed hydrogel. In swelling dynamic and deswelling dynamic tests, a sample of reclaimed hydrogel (0.15 g) is applied. The bag (with polymer) is drowned in 110 mL distilled water in a vessel at lab temperature. For evaluating deswelling dynamic, the swollen superabsorbent polymer (after obtaining balance swelling) is set in a vessel in lab conditions. The influence of temperature is evaluated by conducting dynamic tests at 70 °C. The influence of pH on swelling capability is evaluated by providing solutions with different pH values. The results show that the reclaimed hydrogel has a large capability to take up and store moisture and is suitable in agricultural utilization. It is technically feasible to increase the water retention capability of soil, and therefore reduce irrigation cost. Moreover, the swelling capability rises with temperature, while it declines with the rise in salt or pH denseness. The results indicate that sodium polyacrylate achieved from used diapers can be reclaimed and applied as a moisture absorbing substance in agriculture for a superior irrigation administration.
