Synthesis of GHBA resin accomplished in the following steps is shown in Fig.
About 50 mg of GHBA resin were added to the solution and stirred on a magnetic stirrer for 2 hr and the contents were equilibrated.
The concentration of metal ion in filtrate was determined by the calibration curves and the percentage removal of the metal ions and their distribution coefficient (K.sub.d) on GHBA resin was calculated using following formula
The FTIR spectrum of guar gum and synthesized GHBA resin was analyzed using KBr pellets.
The FTIR spectrum of GHBA resin peak at 2950 [cm.sup.(-1)] is attributed is to C--H stretching vibration.
The degradation of GHBA resin occurred in two stages.
Distribution coefficient ([K.sub.d]) and percentage removal of metal ions from effluent of Paradise Steel Industry, Jodhpur on GHBA resin ([K.sub.d] x [10.sup.2]).
The results of percentage removal of metal ions from effluent of Paradise Steel Industry, Jodhpur by GHBA resin are summarized in Table 2.
Optimum results for the removal of metal ions from the effluent of Paradise Steel Industry, Jodhpur on GHBA resin.
The ion exchange capacity was found to be 3.18 meq [g.sub.(-1)] of the dry GHBA resin.
Quantitative separation of metal ions on GHBA column.
To test the long-term stability of the column containing the GHBA resin, it was subjected to successive adsorption and desorption cycles by passing a metal ion solution through it at the optimum flow rate.
