Synthesis and application of carboxymethylated tamarind kernel gum (Fe loaded) based superabsorbent hydrogels to investigate the effect on marigolds plant growth

Abstract

The iron implemented as SAH was modified by intermixing with Iron microelement in Itaconic acid and carboxymethylated tamarind kernel gum. Different types of samples were prepared for different compositions of SAH by changing the concentration of monomer, initiator and cross linker. Iron chloride was interpenetrated in the best swelled hydrogels for the release of iron as micronutrient. The characterization of synthesized hydrogel and modified FSAH was done by FTIR and SEM analysis. Different behaviors of synthesized hydrogels in terms of weather conditions and pH (3, 8, 10) of soil were studied. The swelling degree was studied by kinetic modeling of iron release and was studied using Higuchi model and Korsmeyer-Peppas model which represent that high number of regression coefficients (R2) more equal to one fitted well in the iron release pattern in water and soil. On the other hand, diffusion quotient (n) showed the Fickian diffusion model found for the procedure of iron release. The FSAH was used for the study of marigold plants. It was also found that the germinated population with FSAH is much higher as compared to without modified SAH.
