Abstract

Synthesis Silica Modified Quaternary Ammines (SMQA) and its application has been carried out on the adsorption of gold(III) ions in a batch system. SMQA material is synthesized through the SMA methylation reaction. SMA material is synthesized from Na2SiO3 and 3-Aminopropyltrimethoxysilane (3-APTMS). Furthermore, the replacement of the methyl group in [-N(CH3)3]+ will change to [-N+CH3{(CH2)3N+(CH3)3}2] called Silica Modified Quaternary Triammines (SMQT). SMQT is synthesized by watching SMA with 3-APTMS become SMT which is then refluxed for methylation process to form SMQT. Material characterization is carried out through identification of functional groups, surface morphological analysis, elemental composition and metal ion concentration. Adsorption process of metal anion [AuCl4]- obtained optimum results at pH 5 with a contact time of 100 minutes with an adsorption capacity of 77.58 mg/g and an efficiency value of 96.975%.
