Utilization of C-Cinnamal Calix[4] Resorcinarene as Adsorbent for Methanil Yellow

Abstract

Rapid population growth causes many the environmental problems. One of them is the pollution of methanil yellow in the water. One of the effective methods in controlling water pollution caused by dyes is the adsorption method with a batch system. C-Cinnamal Calix [4] Resorsinarene (CCCR) compound is a compound synthesized from cinnamon oil waste that has great potential to be developed as adsorbent for dangerous dyes. The purpose of this study is to determine the maximum absorption capacity of CCCR towards methanil yellow using optimum conditions parameters (concentration and contact time). Absorption of methanil yellow in solution by C-Cinnamal Calix [4] resorcinarene (CCCR) compounds is carried out at the optimum pH of 3 with concentration variations of 20, 50, 100, 150 and 200 mg/L. The amount of methanil yellow reaches an absorption capacity of 1.83 mg/g at a concentration of 150 mg/L, while for the contact time is carried out at the optimum pH and concentration with variations in contact time of 30, 60, 90, 120, 150, and 180 minutes. The Results show that the optimum contact time was 150 minutes with an absorption capacity of 2.1375 mg/g.
