Sintesis dan Karakterisasi Senyawa C-Vanillin Kaliks[4]Resorsinarena (CVKR) Sebagai Adsorben Zat Warna Metanil Yellow

Abstract

— Pollution caused by industrial waste is a problem for people's lives, one of which is water pollution by dyes. The synthetic dye is difficult to degrade in nature, so it requires an alternative method to be able to degrade the dye. The compound C-Vaniline Kalix[4]Resorcinarene (CVKR) has great potential as an adsorbent to be developed for dye adsorption. This study aims to determine the potential of C-Vanillin Kaliks [4] resorcinnarene (CVKR) as an adsorbent for the adsorption of metanyl yellow dye using optimum condition parameters to affect the metanyl yellow adsorption process which are estimated. The CVKR obtained was in the form of a peach colored powder solid of 0.833 grams. The results of characterization with FTIR showed absorption peaks at wave numbers 3355.12 cm-1 (O-H), 1508.14 cm-1 (C=C benzene) and 1141.58 cm-1 (C-O), the results of UV-Vis measurements showed the presence of adsorption of conjugated dienes at a wavelength of 299 nm with an absorbance of 3.5582 A and CVKR has a melting point is 380 0 C. Analysis of the adsorption of metanyl yellow by CVKR under optimal conditions occurred at pH 5, concentration 250 mg/L, optimum contact time 90 minutes and stirring speed 200 rpm . Adsorption inclined the langmuir isotherm pattern with a determinant value is 0.9175. The % RSD value of methanyl yellow was 1.3361%. The LOD and LOQ values were 0.27568233 mg/L and 0.91894118 mg/L in the analytical method used.
