Abstract

Adsorpsi Pewarna Sintetik Remazol Brilliant Blue R untuk batik dengan adsorben daun bidara arab (Ziziphus spina-christi) yang telah dikarbonasi 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 (20, 25, 30, 35, 40, 45, 50 dan 55 mg), variasi konsentrasi awal (30, 40, 50, 60, 70, 80, 90, 100 dan 110 ppm) serta variasi pH larutan (1, 2, 4, 6, 8, 10 dan 12). Hasil adsorpsi diukur absorbansinya menggunakan spektrofotometer UV-Vis pada panjang gelombang maksimum 595 nm. Kondisi optimum adsorpsi diperoleh pada waktu kontak 45 menit, massa adsorben 45 mg, konsentrasi awal 100 ppm serta pada pH 1 dengan %dekolorisasi masing-masing sebesar 91,11%; 83,92%; 83,71% dan 98,94%. Metode adsorpsi yang diterapkan menghasilkan %dekolorisasi maksimum sebesar 99,57% dengan kapasitas adsorpsi maksimum sebesar 49,68 mg/g. Pada penelitian ini menggunakan tipe isoterm Freundlich dengan nilai R2 sebesar 0,9943. ========================================================= Adsorption of Remazol Brilliant Blue R synthetic dyes for batik with adsorbents bidara arab’s leaf (Ziziphus spina-christi) was carbonized 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 (20, 25, 30, 35, 40, 45, 50 and 55 mg), variations in initial concentration (30, 40, 50, 60, 70, 80, 100 and 110 ppm) and variations in the pH of the solution (1, 2, 4, 6, 8, 10 and 12). The adsorption results are measured using UV-Vis spectrophotometer at maximum wavelength of 595 nm. The optimum conditions of adsorption were obtained at 45 minutes contact times, mass of adsorbent 45 mg, initial concentration of solution of 100 ppm and at pH 1 with % decolorization respectively 91,11%; 83,92%; 83,71% dan 98,94%. The adsorption method applied produces a maximum %decolorization of 99.57% with a maximum adsorption capacity of 49,68 mg/ g. This study using a Freundlich isotherm type with R2 value of 0.9943.
