Abstract

The effectiveness of charcoal base metallic composite electrodes using commercial activated charcoal was investigated to fabricate an effective and low cost electrode to decolorize textile industries wastewater. The mixture of charcoal-graphite-metal powder (first layer) and graphite powder-polyvinyl chloride (second layer) was mixed together and later pressed at 10 toncm^-2 to form two layers pellet. C.I. Reactive Orange 16 (RO16) was chosen as the model dye because of its high resistance towards conventional treatment methods while NaCl was selected as supporting electrolyte. The electrode efficiencies were determined by percentage of RO16 decolorization. The effect of metal used, PVC percentage, composition of charcoal and graphite and duration of electrolysis time were examined and the results indicated that application of charcoal base metallic composite electrode using pellet with the composition of C₃₀C^G₁₈Sn₁₂PVC₄₀-C^G ₆₀PVC₄₀ able to decolorized RO16 dye up to 83.3% respectively after 2 hours electrolysis time and increase proportionally with increase duration of electrolysis time. The study of activated charcoal base metallic composite electrode illustrated that reduction of PVC percentage also led to enhance in RO16 decolorization percentage. The decolorization of RO16 was determined by the changes of absorption spectrum intensity of azo chromophore (-N=N-) using UV-Vis spectrophotometer at λ = 388 and 492.50 nm.

Abstrak

Penggunaan elektrod komposit logam berasaskan arang menggunakan arang teraktif komersial dikaji untuk menghasilkan elektrod yang efektif dan berkos rendah dalam menyahwarna air buangan industri tekstil. Campuran serbuk arang-grafit-logam (lapisan pertama) dan serbuk grafit-polivinil klorida (lapisan kedua) dicampurkan dan kemudiannya dikenakan tekanan 10 tancm^-2 untuk menghasilkan dua lapisan pelet. C.I. Reaktif Oren 16 (RO16) dipilih sebagai pewarna contoh kerana ketahanannya yang tinggi terhadap kaedah perawatan konvensional manakala NaCl dipilih sebagai elektrolit penyokong. Keberkesanan elektrod ditentukan oleh peratus penyahwarnaan RO16. Kesan jenis logam yang digunakan, peratus PVC, komposisi arang dan grafit serta tempoh masa elektrolisis dikaji dan hasil kajian menunjukkan bahawa penggunaan elektrod komposit logam berasaskan arang menggunakan pelet dengan nisbah C₃₀ C^G ₁₈Sn₁₂PVC₄₀-C^G ₆₀PVC₄₀ berjaya menyahwarnakan RO16 sehingga 83.3% selepas 2 jam masa elektrolisis dan berkadar terus dengan peningkatan tempoh elektrolisis. Kajian terhadap elektrod komposit logam berasaskan arang teraktif menunjukkan bahawa penurunan peratus PVC juga membawa kepada peningkatan peratus penyahwarnaan RO16. Penyahwarnaan RO16 ditentukan oleh perubahan keamatan spektrum penyerapan kromofor azo (-N=N-) menggunakan spektrofotometer UV-Nampak pada λ = 388 dan 492.50 nm.
