Abstract

Silica gel is a compound that has two active sides, namely silanol (S-OH) and siloxane (Si-O-Si), which are still less effective as adsorbents, so modification is carried out. Silica is modified by adding sulfonate compounds with the help of GPTMS bridging compounds. This modification aims to improve the absorption capacity of Nickel (Ni2+) metal ions in the modified adsorbent, namely sulfonate-modified silica gel-GPTMS. The characterizations used are SSA (Atomic Absorption Spectrophotometry) to see the success of the adsorption and desorption process. This research is quantitative experimental research where the adsorption and desorption processes are carried out using the column method, where the adsorption process itself is carried out on the Ni2+ cation using silica gel-GPTMS Sulfonate adsorbent at an optimal concentration of 20 ppm and pH 3. Then, we continued with the desorption process, which aims to determine the optimum conditions of the desorption process, including determining the type of desorption agent (NaCl and CaCl2) and concentration for the Ni2+ cation desorption process. Based on the results of the research conducted, the optimum condition of the type of desorption agent is CaCl2 where the desorbed weight is 0.1527 mg, and the per cent desorption is 90.10%, the optimum concentration of CaCl2 is 0.025M with a desorbed weight of 0.1442 mg and a per cent desorption of 90.18%. Based on the experimental results, the sulfonate-modified silica gel-GPTMS adsorbent can still be used repeatedly for adsorption and desorption of Ni2+ cations at optimum conditions.

Abstract

Silica gel is an adsorbent often used in chromatography columns as a resin or stationary phase. Silica gel has active groups on its surface in the form of silanol (-SiOH) and siloxane (-Si-O-Si-). The effectiveness of silica gel in absorbing heavy metal ions is very low, so modification is needed to increase the absorption capacity of silica gel to metal ions. The addition of sulfonate with the GPTMS linkage compound dose modification. Adsorption and desorption are two methods that can be used to separate manganese metal. This research aims to obtain the optimum desorption agent (NaCl and CaCl2) and the concentration of the AAS-characterised desorption agent. This study used the column method for the adsorption and desorption process. This study used the column method for the adsorption and desorption process. The column method is a technique used to separate certain substances from a mixture by utilizing the interaction between adsorbent and adsorbate. The results obtained optimum desorption agent CaCl2 where the weight desorbed 0.1168002 mg with a percent desorption of 92.3%, the optimum concentration of CaCl2 0.05 M where the weight desorbed 0.132264 mg with a percent desorption of 95% Adsorbent characterization was conducted with FTIR and XRF.

Abstract

Silica gel is one of the adsorbents widely used in adsorption, but silica gel has a low ability to absorb metals. Hence, modifications need to be made to improve it. Silica gel modified using sulfonate groups from monosodium salt compound of 4-amino-5-hydroxy-2,7-naphthalene disulfonic acid using GPTMS coupling compound for adsorption and desorption of Fe3+ ions by column method was carried out. The adsorption process of Fe3+ ions using silica gel-GPTMS-sulfonate has been carried out in previous studies and obtained an optimum state at pH 6 and a concentration of 20 ppm. After the adsorption process is carried out, the desorption process is continued with variations in the type of desorption eluent and concentration variations. The types of desorption agents are NaCl, CaCl2, HCl, and HNO3, with the optimum desorption agent being HNO3 with a release of 0.077517 mg of Fe3+ ions from 0.1587403 mg of Fe3+ ions absorbed and a desorption percentage of 48.83%. The concentration variations are 0.5 M, 1 M, 2.5 M, and 5 M, with an optimum concentration of 2.5 M HNO3 with a release of 0.098505 mg Fe3+ ions and a desorption percentage of 64.43%.
