| Abstract: | In this paper the infrared spectral changes and thermal gravimetric analysis of the gels formed with carboxymethyl hydroxypropyl guar gum (CMHPG) cross linked with metal ions(Fe 3+ ,Cr 3+ ,Ti 4+ ) have been studied.The results indicated that the coordinated active sites are mainly supplied with hydroxypropyl,neigbouring cis OH of main chain and carboxymethyl groups of CMHPG.And the results of spectral analysis showed the strength orders and coordinated mode of the guar gum cross linked with metal ions. |
