Adsorpsi Ion Timbal(Ii) Menggunakan Lempung Maredan Teraktivasi Naoh

---

Maredan natural clay is one of the natural clay sources from Desa Maredan, Kecamatan Tualang, Kabupaten Siak, Provinsi Riau. Previous research had successfully demonstrated that Maredan natural clay has the potential to be applied as an adsorbent for various adsorbates, particularly heavy metal ions such as lead(II) ions. The adsorption capacity of the clay can be enhanced through activation. Chemical activation using NaOH was expected to increase the surface area and the number of active sites on the clay. The purpose of this reaserch was to analyze the effect of activating Maredan clay on its adsorption capacity, determine the optimum adsorbent dose, and the optimum pH of the solution for lead(II) ion adsorption by NaOH-activated Maredan clay. The method used in this reaserch was batch adsorption of lead(II) ions, considering activation parameters including the effect of varying NaOH activator concentrations (0.5; 1; 2; 3 and 4 M), adsorption parameters including the effect
of varying adsorbent doses (0.25; 0.5; 1.0; 1.5 and 2.0 g), determining the pHpzc, and the effect of varying solution pH (pH 2, 4, 6, 8 and 10). The Maredan clay adsorbent was characterized using SEM-EDS and FT-IR. The results indicated that the optimal adsorption conditions were achieved with a NaOH activator concentration of 3 M, an adsorbent dose of 0.5 g, and a pH of 8, with an adsorption efficiency of 79.84% and an adsorption capacity of 3.1258 mg/g. The pHpzc value of the NaOH-activated Maredan clay was 6.2. These results were higher than those obtained in a previous study by Nazila (2023), which used non-activated Maredan clay for adsorbing lead(II) ions, showing an adsorption efficiency of 77.02% and an adsorption capacity of 0.4106 mg/g, it can be concluded that activating Maredan clay with NaOH can enhance its adsorption capability for lead(II) ions.
