Treatment of rhodamine b and acid red 18 by electrocoagulation using iron electrode

Treatment of rhodamine b and acid red 18 by electrocoagulation using iron electrode / Muhammad Akmal Zulkifli
Proses elektro-penggumpalan (EC) adalah proses elektrokimia yang memperkenalkan bahan gumpal dan menghilangkan pepejal terampai, bahan koloid, logam, dan lain-lain pepejal terlarut dari air buangan. Dalam kajian ini, Asid Merah 18 (AR18) dan Rhodamine B (RhB) digunakan sebagai air kumbahan sintetik. Parameter yang terlibat dalam kajian ini adalah kepekatan awal larutan pewarna, ketumpatan arus dan masa EC. Kecekapan proses EC ditentukan oleh persilangan penyingkiran warna dan permintaan oksigen kimia (COD). Telah didapati bahawa kepekatan awal yang semakin meningkat akan mengurangkan kecekapan penyingkiran bagi kedua-dua larutan pewarna. Sementara itu, kepadatan arus optimum yang 50 A/m2 akan meningkatkan kecekapan warna dan penyingkiran COD. Untuk pembolehubah waktu EC, masa rawatan yang optimum untuk AR18 adalah 1 jam, manakala masa optimum untuk RhB adalah 2 jam. _______________________________________________________________________________________________________ The electrocoagulation (EC) process is an electrochemical process that introducing coagulants and removing suspended solids, colloidal materials, metal, and other dissolved solids from wastewaters. In this study, Acid Red 18 (AR18) and Rhodamine B (RhB) are used as synthetic wastewater. The parameter involved in this study are initial concentration of dye solution, current density and electrocoagulation time. The process efficiency of EC was determined by percentages removal of colour and chemical oxygen demand (COD). It was found that the increasing initial concentration will reduce removal efficiencies for both dyes solutions. Meanwhile, optimum current density which is 50 A/m2 will increase the efficiencies of colour with 95% for AR18 and 70% for RhB and COD removal with 83% for AR18 and 43% for RhB. For EC time variables, the optimum time of treatment for AR18 is 1 hour, while optimum time for RhB is 2 hours with efficiencies 91% and 87% respectively.
