| Abstract | ||
| In the present study, hydrazine derivative has been synthesized. Its Thiocarbohydrazide (1) from the condensing of carbon disulfide and hydrazine hydrate. Compound 4-(2-amino-2-(2-amino-5-mercapto-1,2,4-triazole-3-yl(ethyl) phenol was synthesized through the hydrophilic environment reaction (with out solvent) ,that is ,thermal fusion reaction between thiocarbohydrazide and tyrosine materials. Also, the chelating resin (3) was prepared from the condensation reaction of compounds 4-(2-amino-2-(2-amino-5-mercapto-4-H-1,2,4-Triazole-3-yl)ethyl) phenol and Tyrosine with phenol and formaldehyde solution in presence of sodium hydroxide under refluxing conditions. The structures of the prepared compounds were characterized (identified) by using FT-IR ( infrared) , 1H –NMR,13C-NMR proton ,carbon nuclear magnetic resonance ) spectra for some of them. The analytical professional for the prepared chelating resin (3) which carrying the compound 4-(2-amino-2-(2- amino-5-mercapto-4-H-1,2,4-Triazole -3-yl)ethyl) phenol and Tyrosine was studied by using one meal method on the transition Pb ion (Pb+2 ) through the evaluating the effect of dealing(treatment) time and PH on the carrying capacity of the resin with fixing the other factors like temperatures, concentration of the studied ion and the amount of resin. The results of max. loading capacity results for ion on the resin as illustrated in figures (1,2) and after the studying ,it was found that the carrying capacity increasing with increasing the time annealing. | ||
