Abstract
One way to reduce Lead (II) levels is by the adsorption process using HVS paper. HVS paper is made adsorbent because it has cellulose content in it which will bind the metal Lead (II). The purpose of this research is to study the effect of adsorbent, adsorbate concentration, contact time and pH of adsorbate absorbed in the adsorbent from HVS paper and determine the adsorption capacity (Qe) and the efficiency of adsorption (%). HVS paper adsorbents were made by turning into a pulp using a 10% w / v NaHCO3 solution, afterward, it was refluxed using 5% w / v Na2HPO4. The adsorption process was carried out using the Batch method, with a mass variation of 0.06; 0.08; 0.1; 0.12; and 0.14 g, concentration variation of 75, 90, 105, 120 and 135 ppm, contact time variation of 5, 10, 15, 20, 25 minutes, and, pH variation of 3, 4, 5, 6, and 7. Furthermore, the characteristics of the adsorbent were performed with Fourier Transform Infrared Spectroscopy (FTIR) and there was a functional group such as –OH, C–H, C = O, and C–O which helped bind the metal Lead (II) in the adsorption process. The characteristics of the adsorbent with a Scanning Electron Microscope (SEM) showed a fiber-like shape with agglomerated fine particles. In order to find out the metal content of Lead (II) that was absorbed, an analysis was carried out using Atomic Absorption Spectrophotometer (AAS). Analysis results showed the optimum adsorption of HVS paper was carried out at a mass of 0.1 g in 105 ppm meeting the Lead (II) requirements with a contact time of 10 minutes and pH of solution 5.
