Abstract

Optimasi kondisi adsorpsi pewarna sintetis Remazol Red 5B dengan adsorben karbon aktif telah dilakukan. Remazol Red 5B merupakan zat warna reaktif yang sulit diuraikan sehingga dapat memberikan dampak negatif bagi lingkungan sekitar apabila limbahnya langsung dibuang tanpa pengolahan. Metode adsorpsi dilakukan untuk mengurangi konsentrasi zat warna Remazol Red 5B di lingkungan. Proses adsorpsi pada penelitian ini menggunakan metode batch. Larutan hasil adsorpsi diukur absorbansinya menggunakan spektrofotometer UV-Vis pada panjang gelombang maksimum. Pengaruh waktu kontak, massa adsorben, konsentrasi awal larutan zat warna, serta pH larutan zat warna dipelajari untuk mendapatkan kondisi optimum yang dapat menghasilkan % removal dan kapasitas adsorpsi maksimum. Waktu optimum untuk adsorpsi Remazol Red 5B menggunakan karbon aktif adalah 90 menit dengan % removal sebesar 85,67%, massa adsorben optimum 10 mg dalam 25 mL larutan dengan % removal 85,67%, konsentrasi awal optimum sebesar 100 ppm dengan % removal sebesar 91,10%, serta pH optimum pada pH 3 dan 13 dengan % removal masing-masing sebesar 100,00%. Kapasitas adsorpsi maksimum yang dapat diperoleh adalah 321,76 mg/g.

Optimization of adsorption conditions of Remazol Red 5B synthetic dyes with activated carbon adsorbent has been researched. Remazol Red 5B is a reactive dyestuff that is difficult to decipher so that it can have a negative impact on the environment if the waste is discharged directly without any treatment. The adsorption method was used to reduce the concentration of Remazol Red 5B dyes in the environment. The adsorption process in this study used a batch method. The absorbance of adsorption solution was measured using a UV-Vis spectrophotometer at the maximum wavelength. The effect of contact time, adsorbent mass, initial concentration of the dye solution, and pH of the dye solution were studied to obtain optimum conditions that can produce maximum % removal and maximum adsorption capacity. The optimum time for adsorption of Remazol Red 5B using activated carbon is 90 minutes with % removal of 85.67%, optimum mass of adsorbent 10 mg in 25 mL solution with % removal 85.67%, optimum initial concentration of 100 ppm with % removal of 91. 10%, and the optimum pH at pH 3 and 13 with % removal each of 100.00%. The maximum adsorption capacity is reaching 321.76 mg /g.
