Abstract
The high development of science and technology affects the economic growth and industrialization process. The industrialization process produces industrial waste which contain heavy metal such as copper (Cu). This industrial waste can harm the environment surronding industrial areas where 15 million or 6% of the Indonesian population live. In order to overcome this problem, mesoporous silica material Santa Barbara Amorphous-15 (SBA-15) is used as an adsorbent. SBA-15 was synthesized through sol gel process using tetraorthosilicate as precursor, Pluronic 123 triblock copolymer as template, and (3-chloropropyl)trimethoxysilane (CPTMS) as functionalized agent. CPTMS was used to modify the SBA-15 surface in order to improve the materials as adsorbent. The materials were characterized using SAXRD and TEM to study material’s cristallinity and pore structure, the presence of organic group was examined using FTIR, the surface area of SBA-15 and SBA-15 CPTMS were characterized using Brunauer Emmett Teller (BET) N2 adsorption isotherm test at 77 K, and the ions concentration in solution after adsorption process was determined using AAS. The crystal structure of SBA-15 and SBA-15 CPTMS was found 2D heksagonal with a more regular SBA-15 pore structure than SBA-15 CPTMS. The surface area of SBA-15-CPTMS was found to be lower than SBA-15, 711.061 m2/g in comparison to 831.996 m2/g. However, in copper adsorption test, it was found that SBA-15-CPTMS has higher adsorption ability.
Highlights
IntroductionHigh industrialization rate in Indonesia is directly proportional to the level of environmental pollution [1]
The high development in science and technology indirectly affected economic growth which is accompanied by rapid industrialization process in Indonesia
It means that 15 million or 6% of the Indonesian population who live in industrial areas or surrounding areas can be affected by heavy metals massive pollution [2]
Summary
High industrialization rate in Indonesia is directly proportional to the level of environmental pollution [1]. It means that 15 million or 6% of the Indonesian population who live in industrial areas or surrounding areas can be affected by heavy metals massive pollution [2]. Environmental Pollution can be caused by heavy metals such as lead, copper, and cadmium which can be found in the water and soil. Synthesis SBA-15 using pluronic 123 will use as copper heavy metals absorbent materials.
