Abstract
Adsorpsi Pewarna Sintetik Remazol Brilliant Blue R untuk batik dengan adsorben karbon aktif telah dilakukan. Pewarna batik apabila langsung dibuang ke saluran air dapat menyebabkan pencemaran lingkungan sehingga harus diolah terlebih dahulu sebelum dibuang untuk mengurangi konsentrasinya. Metode adsorpsi merupakan salah satu metode yang efektif dalam penurunan konsentrasi pewarna batik Remazol Brilliant Blue R. Beberapa parameter yang dipelajari dalam penelitian ini adalah variasi waktu kontak (10, 20, 30, 40, 45 dan 50 menit), variasi massa adsorben (2,5; 5,0; 7,5; 10,0; 12,5; 15,0; 20,0 dan 25,0 mg), variasi konsentrasi awal (10, 20, 40, 60, 80, 100 dan 120 ppm) serta variasi pH larutan (2, 4, 6, 8, 10 dan 12). Hasil adsorpsi diukur absorbansinya menggunakan spektrofotometer UV-Vis pada panjang gelombang maksimum 592 nm. Kondisi optimum adsorpsi diperoleh pada waktu kontak 40 menit, massa adsorben 20 mg, konsentrasi awal 100 ppm serta pada pH 2 dengan %dekolorisasi masing-masing sebesar 72,54%; 90,94%; 90,79% dan 99,39%. Metode adsorpsi yang diterapkan menghasilkan %dekolorisasi maksimum sebesar 99,39% dengan kapasitas adsorpsi maksimum sebesar 123,05 mg/g. Pada penelitian ini menggunakan tipe isoterm Freundlich dengan nilai R2 sebesar 0,9822.

Adsorption of Remazol Brilliant Blue R Synthetic Dyes for batik with activated carbon adsorbents has been carried out. Batik dyes when discharged directly into waterways can cause environmental pollution so it must be treated before being discharged to reduce its concentration. The adsorption method is one of the effective methods in reducing the concentration of Remazol Brilliant Blue R. batik. Some parameters studied in this study are variations in contact time (10, 20, 30, 40, 45 and 50 minutes), variations in the mass of adsorbent (2.5; 5,0; 7.5; 10,0; 12.5; 15,0; 20,0 and 25,0 mg), variations in initial concentration (10, 20, 40, 60, 80, 100 and 120 ppm) and variations in the pH of the solution (2, 4, 6, 8, 10 and 12). The adsorption results are measured using UV-Vis spectrophotometer at maximum wavelength of 592 nm. The optimum conditions of adsorption were obtained at 40 minutes contact times, mass of adsorbent 20 mg, initial concentration of solution of 100 ppm and at pH 2 with % decolorization respectively 72.54%; 90.94%; 90.79% dan 99.39%. The adsorption method applied produces a maximum %decolorization of 99.39% with a maximum adsorption capacity of 123,05 mg/ g. This study using a Freundlich isotherm type with R2 value of 0.9822.
