2.3.2 Leaching tests A heavy metal leaching test from fly ash and Na-A zeolite was investigated in aqueous solutions in both acid and alkaline media, adjusted by hydrochloric acid and sodium hydroxide solutions. Suspensions containing 0.05 g of zeolite and fly ash, in 10 ml of solution at pH values of 2, 5, 7, 9, and 11, were agitated for 24 h at 100 rpm (Gerhardt Laboshake). The pH of the leachate was measured using a pH meter (Mettler-Toledo), and samples were filtered and analyzed by ICP-MS (Perkin Elmer ICP-MS, Optima 8300). 使用格哈特振荡器100rpm振荡24小时
2.3.3 Adsorption studies of Cr (III) Batch tests were conducted to determine the metal adsorption by shaking at 100 rpm (Gerhardt Laboshake), 0.05 g of zeolite, and 10 ml of Cr3+ solutions with different concentrations. The experiments were performed in closed flasks at room temperature (25 +- 2⁰ C) in duplicate, pH values (Mettler Toledo, pH-meter) were monitored at each sample withdrawal. Isotherm data were obtained after reaching an equilibrium time of 24 h. All samples were filtered using a membrane of 0.45 m pore size prior to measurements of Cr3+ concentrations by ICP-MS (Perkin Elmer ICP-MS, Optima 8300). The adsorption capacity (qe) of zeolite was calculated by Eq. (1) where C0 and Cf are the initial and final metal ion concentrations, respectively, Va is the aqueous phase volume and M is the weight of zeolite used.
