Web4 apr. 2024 · 3.2 Effect of PH. The experiment has been conducted for cadmium removal efficiency with SCB as an adsorbent. The pH was varied from different range (3.2, 5.2, 7.2, and 9.2) for SCB and the other parameters remained constant. The pH of the solution was adjusted by adding NaOH or H2SO4 to get the desired pH. Cadmium is a chemical element with the symbol Cd and atomic number 48. This soft, silvery-white metal is chemically similar to the two other stable metals in group 12, zinc and mercury. Like zinc, it demonstrates oxidation state +2 in most of its compounds, and like mercury, it has a lower melting point than the transition metals in groups 3 through 11. Cadmium and its congeners in group 12 are ofte…
