Abstract

Adsorpsi campuran tiga jenis pewarna (remasol kuning, indigosol kuning, dan naftol kuning) dengan adsorben karbon aktif telah dilakukan. Pewarna batik apabila langsung dibuang ke saluran air dapat menyebabkan pencemaran lingkungan. Metode adsorpsi merupakan salah satu metode yang efektif dalam penurunan konsentrasi pewarna batik remasol kuning, indigosol kuning, dan naftol kuning. Tiga jenis pewarna dicampur menjadi satu sebagai larutan model untuk dapat mengetahui kondisi adsorpsi optimum campuran pewarna yang nantinya dapat diterapkan dalam pengolahan limbah pewarna batik. Beberapa parameter yang dipelajari dalam adsorpsi campuran pewarna adalah variasi waktu kontak, variasi massa adsorben, dan juga variasi konsentrasi awal. Hasil adsorpsi diukur absorbansinya menggunakan spektrofotometer UV-Vis pada panjang gelombang maksimum masing-masing pewarna. Kondisi optimum adsorpsi diperoleh pada waktu kontak 50 menit dengan %Removal masing-masing pewarna 74,73%; 90,57% dan 93,50%; massa adsorben 16 mg dengan %Removal masing-masing pewarna 74,61%; 89,22%; 92,32%; dan konsentrasi awal pada 25 mg/L dengan %Removal masing-masing pewarna 69,48%; 69,15%; dan 75,08%. Kapasitas adsorpsi maksimum masing-masing pewarna diperoleh pada 40,38; 54,18; dan 83,12 mg/g.

Adsorption of three types of dyes (remazol yellow, indigosol yellow, and naphtol yellow) with activated carbon adsorbent has been carried out. Batik dye when disposed directly to the airways can cause environmental problem. The adsorption method is one of the effective methods that can decrease the concentrations of batik dyes remazol yellow, indigosol yellow, and naphthol yellow. Three types of dyes were mixed as artificial solution to be able to determine the adsorption conditions of mixture dyes that can be applied in processing batik dye waste. Some parameters learned in the adsorption of mixture dyes were variations in contact time, variations in mass of the adsorbent, as well as initial variations in concentration. The adsorption results must be adapted using a UV-Vis spectrophotometer at the maximum wavelength of each dye. The adsorption optimum were obtained at contact time 50 minutes with %Removal of each dyes 74.73%; 90.57%; and 93.50%; adsorbent mass 16 mg with %Removal of each dyes 74.61%; 89.22%; 92.32%; and initial concentration of each dye 25 mg/L with %Removal of each dye 69.48%; 69.15%; and 75.08%. Maximum adsorption capacity of each dye were 40.38; 54.18; dan 83.12 mg/g.
