Kapasitas Adsorpsi Metilen Biru Dan Luas Permukaan Lempung Cengar Teraktivasi Asam Sulfat

---

Synthesis of liquid coagulant Cengar clay calcination at 700oC for 3 hours, which was activated using sulfuric acid 0.2; 0.4 and 0.6 mol produced a solid by product. This side product was called activated solids sulfuric acid (LCA), which could potentially be used as an adsorbent. Before applied as an adsorbent, LCA was heated at a temperature of 230oC for 5 hours. In this study, the activated solid sulfuric acid was used as an adsorbent for the adsorption of methylene blue dye in water. The surface area of the Cengar clay activated sulfuric acid was determined by the maximum adsorption capacity obtained from the Langmuir equation. Cengar clay adsorption capacity was determined by the effect of stirring time, temperature and concentration of the adsorbate adsorption to methylene blue. The results showed that the maximum adsorption capacity of methylene blue in the range from 1.9988 to 3.8402 mg/g and a surface area of Cengar clay activated sulfuric acid in the range from 4.2739 to 14.2382 m2/g. The maximum adsorption capacity (Qm) of methylene blue and the surface area of Cengar clay activated sulfuric acid was highest in the adsorbent LCA0,6 with conditions stirring time of 10 minutes, at a temperature of 50°C and adsorbat concentration of 40 ppm.
Keywords: Activated clay, calcination, sulfuric acid, surface area, adsorption capacity
