PREPARATION AND ANALYSIS OF POLY (ACRYLAMIDE-GUAR GUM) HYDROGEL

Abstract

As we as a whole know the significance of green science combination and portrayal of ecological benevolent changed regular polymers is need of time. These regular polysaccharides additionally dispose of the risk to wellbeing and condition. Guar gum is one of the significant normally happening polymer having wide applications because of its rheological adjusting properties in therapeutic, pharmaceutical, food, material and scores of other modern and business divisions. There has been wide investigation on physiochemical and pharmaceutical properties of guar gum yet concentrate on adjusted guar gum and its subsidiaries are very inadequate. Unmodified guar gum has certain downsides like absence of lucidity and free streaming properties, fall in thickness and turbidity on draw out remain, and so on. These disadvantages can be overwhelmed by altering and derivatives of guar gum and can be utilized in multidiscipline fields. In this work I have all set hydrogels of Polyacrylamide-Guar gum hydrogels using glutaraldehyde as cross linker and potassium persulphate as initiator. Hydrogels with varying concentration of cross linker and guar gum were prepared and their swelling with admiration to time and temperature were studied. The effect of concentration of cross linker and guar gum on the inflammation of the hydrogel was calculated. The hydrogels were described by FTIR spectroscopy and TGA. Percentage swelling was chosen as the parameter for deciding the paramount hydrogel in each series of the guar gum concentration. The hydrogels showed considerable swelling and also the swelling exponent was found to be in the range of 0.919-0.997 thus, indicating the non-fickian diffusion mechanism. The regression coefficient was found to be 0.992-0.995.
