| Popis: | This work investigates removing the Malachite Green (MG) dye, the poly acrylic hydrogel beads used as a surface to adsorb the dye, the isotherm of adsorption was examined and aspects that influence it, like increasing heat, adding salt, the influence of dry beads and effect of shaking. according to the results, the effect of the adsorption has been found that it is matched to the Friendlish equation much more than Langmuir and Temkin equations. A positive relationship between the adsorption process and the increase in temperature is found that adsorption increases when the temperature increase. Also, the adsorption increased when the salt was added at a temperature (of 20 C0). As that the adsorption doesn’t budge by adding either dry or wet beads of poly acrylic. The thermodynamic function was calculated (ΔH, ΔS, ΔG). The kinetic parameters were examined by the Lagergren equation to first order, for second-order equations either, according to the results of experimental data showing us that the adsorption obeys the pseudo-second order more than the first-order. |
