Degradasi Zat Warna Kongo Merah Limbah Cair Industri Tekstil Di Kabupaten Pekalongan Menggunakan Metode Elektrodekolorisasi

Abstract

ABSTRAKDegradasi zat warna kongo merah limbah cair industri tekstil menggunakan metode elektrodekolorisasi telah dilakukan. Eksperimen dilakukan dengan mengelektrolisis kongo merah menggunakan katoda karbon dan anoda besi. Analisis konsentrasi kongo merah dilakukan menggunakan metode spektrofotometri. Hasil penelitian menunjukkan bahwa dibawah kondisi optimum pada voltase 12 V-jarak elektroda 1 cm-pH 4-konsentrasi H 2 O 2 500 mg/L selama 12 menit, zat warna kongo red limbah cair industri tekstil dapat didegradasi 99,83 %. Metode ini dapat digunakan untuk mendegradasi zat warna kongo merah.Kata kunci : kongo merah, metode elektrodekolorisasi, limbah cair industri tekstil DEGRADATION OF CONGO RED DYE OF TEXTILE INDUSTRIAL WASTEWATER AT PEKALONGAN REGENCY USING ELECTRODECOLORIZATION METHOD ABSTRACTDegradation of congo red dye of textile industrial wastewater using electrodecolorization method has been done. The experiment have been performed by electrolysis of congo red using carbon cathode and iron anode. Analysis of congo red concentration using spectrophotometric method. The result of the research showed that under the optimum conditions of 12V voltage -1 cm electrode distance -pH 4 -500 mg/L H 2 O 2 for 12 minutes, congo red dye of textile industrial wastewater can be degraded 99.83%. This method can be applied to degradation of congo red dye.

Congo Red Dye Adsorption using Magnesium Hydroxide from Seawater Bittern

“…The pseudo-first-order and pseudo-second-order are the most widely used models to study the adsorption kinetics of dyes and measure the rate of adsorption [29]. The adsorption kinetics of CR dye with Mg(OH)2 from seawater bittern was tested using the Lagergren pseudo-first-order model, as in equation ( 4), and the pseudo-second-order Ho shown in equation (5). Where qe and qt are adsorption capacity at equilibrium and at time t (mg/g), k1 and k2 are rate constants of pseudo-first-order and pseudo-secondorder [30,31].…”

“…Congo red is a reactive dye often used in the textile industry, mainly in cotton fabrics. This dye is very soluble in water and produces a red solution that cannot be degraded biologically (recalcitrance) [4,5].…”

Synthesis NiFe2O4 Nanoparticles by co-Precipitation Method for Degradation of Congo Red Dye

“…The band gap energy of NiFe2O4 nanoparticles was calculated using the Tauc method. The graph was plotted between hv versus ahv 2 . The band gap energy of NiFe2O4 nanoparticles was 3,15 eV.…”

“…The azo dye of Congo red, is one of the organic dyes that are reactive and many used for industrial of textile. This dye is soluble in water and non-biodegradable [2] is an anionic organic dye with a benzidine structure that has molecule formula C32H22N6Na2O6S2 and weight molecule 696.99 g/mol. Congo red has changed the pigment from blue to red at pH 3.0-5.2 [3].…”
