Abstract

The purpose of this research is to generate wheat straw based super absorbent which is eco-friendly. The chemical approach of graft-copolymerization is used to create this novel super absorbent polymer. Polyacrylic acid is the building block polymer that is utilized in the production of highly absorbent polymer. Furthermore, water absorption capabilities of these environmentally friendly absorbents are investigated in a variety of conditions and then compared to one another. The polymer is then tested for absorbency. It is discovered that several optimized factors, such as the time span of the immersed sample, the effect of different solutions, and the temperature, has an impact on the absorbencies of the super absorbent. Optical microscope pictures provided proof of the morphological characteristics. The excellent product is achieved with absorbencies of 251 percent in distilled water and 528.34 percent in a 4-weight percent sodium hydroxide solution, respectively. It is also discovered that the absorbency increased in accordance with the increase in temperature. At 80 degrees Celsius, the maximum absorbency is observed in water, at 548.6 percent.
