Abstract

Adsorpsi campuran pewarna remazol brilliant blue R and remazol yellow FG dengan adsorben karbon aktif daun bidara arab (Ziziphus spina-christi) telah dilakukan. Limbah pewarna cair dari proses pencelupan, pewarnaan atau pencucian industri batik merupakan sumber pencemaran linkungan bila langsung dibuang ke badan air sehingga perlu diturunkan konsentrasinya sebelum dibuang ke lingkungan. Metode adsorpsi dinilai paling efektif karena kemampuannya untuk menurunkan konsentrasi limbah pewarna. Parameter yang dipelajari dalam penelitian ini adalah waktu kontak (10, 20, 30, 40, 45 dan 50 menit), variasi massa adsorben (30, 35, 40, 45, 50, dan 55 mg), variasi konsentrasi awal masing-masing pewarna (24, 26, 28, 30, 32, dan 34 mg/L), dan variasi pH larutan (2, 3, 4, 6, 8, 10 dan 12). Hasil adsorpsi diukur absorbansinya dengan spektrofotometer UV-Vis pada panjang gelombang maksimum masing-masing pewarna. Kondisi optimum adsorpsi diperoleh pada waktu kontak 40 menit dengan %removal remasol biru dan remasol kuning dalam campuran pewarna sebesar 92,08% dan 20,96%; massa adsorben 40 mg dengan %removal masing-masing pewarna sebesar 94,20% dan 28,18%; konsentrasi awal pada 24mg/L dengan %removal masing-masing pewarna sebesar 97,31% dan 36,32%; pH larutan pada pH 2 dengan %removal masing-masing pewarna sebesar 100% dan 71,5%. ===================================================================================================== The adsorption of a mixture dyes of remazol brilliant blue R and remazol yellow FG dye with adsorbents bidara arab’s leaf (Ziziphus spina-christi) was carbonized has been carried out. Liquid dye waste from the dyeing or washing process of the batik industry is a source of environmental pollution if it is directly discharged into water bodies Therefore, it is necessary to reduce its concentration before being discharged into the environment.. The adsorption method is considered the most effective because of its ability to reduce the concentration of dye waste. The parameters studied in this study were contact time (10, 20, 30, 40, 45 and 50 minutes), variations in adsorbent mass (30, 35, 40, 45, 50, and 55 mg), variations in the initial concentration of each dye (24, 26, 28, 30, 32, and 34 mg/L), and pH variations in solution (2, 3, 4, 6, 8, 10 and 12). The adsorption results were measured with UV-Vis spectrophotometer at the maximum wavelength of each dye. The optimum adsorption conditions were obtained at a contact time of 40 minutes with the percentage of remazol blue and remazol yellow in mix dyes solutions is 92,08% and 20,96%; adsorbent mass of 40 mg with %removal of each dye is 94,20% and 28,18%; initial concentration at 24mg/L with %removal of each dye is 97,31% and 36,32%; The pH 2 of the solution with %removal of each dye was 100% and 71,5%.
