“…The SEM micrographs were obtained using an accelerating voltage of 15 kV to evaluate the effectiveness of electrochemical oxidation before and after treatment (Figure 3). Figure 3(b), the process clearly affects the electrode surface, creating many pores that allow pollutants to enter; thus leading to an electrochemical oxidation reaction occurring inside the electrode [26,27] and resulting in a working electrode for landfill leachate treatment.…”

Charcoal powders obtained from commercially available charcoal and the open burning of palm oil, rubber, coconut, and mangrove trees were used to fabricate composite electrodes in this study. A weight portion of charcoal powder, graphite, cobalt, and polyvinyl chloride (C-C G -Co-PVC) were mixed in tetrahydrofuran (THF). The fabricated composite electrodes were then used as working electrodes for the electrochemical treatment of landfill leachate samples. A variable pressure scanning electron microscope (VPSEM) was used to examine the appearance of the charcoal powder. The results showed that rubber tree charcoal powder is the best charcoal powder for fabricating the composite electrodes, as it has various pore sizes and more surface area available for adsorption and reaction. Field emission scanning electron microscopy (FESEM) was performed before and after electrolysis of the landfill leachate. The results revealed that the presence of voids on the electrode surface before and after electrolysis improved the electrochemical oxidation of the landfill leachate, and yielded removal percentages in colour, COD, NH 3 -N, and total P of not less than 80%, 91%, 73%, and 84%, respectively. Keywords: landfill leachate, charcoal powder, composite electrode, electrochemical method Abstrak Serbuk arang yang diperoleh dari arang komersil dan pembakaran terbuka batang-batang pokok kelapa sawit, pokok getah, pokok kelapa, dan pokok bakau telah digunakan untuk membina elektrod komposit berasaskan arang hasil gabungan serbuk arang, grafit, kobalt dan polivinil klorida (C-C G -Co-PVC) yang telah dicampurkan mengikut komposisi berat tertentu dalam pelarut tetrahidrofuran (THF). Elektrod komposit yang telah dibina kemudiannya digunakan sebagai elektrod kerja untuk merawat sampel air bahan larut lesap melalui kaedah elektrokimia. Mikroskop elektron imbasan tekanan boleh ubah (VPSEM) telah digunakan untuk mengkaji sifat fizikal serbuk arang. Keputusan menunjukkan bahawa serbuk arang pokok getah merupakan serbuk arang terbaik untuk membina elektrod komposit dalam kajian ini kerana ia mempunyai banyak liang dan luas permukaan yang lebih tinggi untuk penjerapan dan tindak balas berlaku. Mikroskop imbasan elektron medan pancaran (FESEM) telah digunakan untuk memerhati permukaan elektrod yang telah disediakan sebelum dan selepas elektrolisis bahan larut lesap. Keputusan menunjukkan bahawa terdapat kehadiran lohong pada permukaan elektrod sebelum dan selepas elektrolisis. Hal ini

“…Phenolic organics and dyes commonly existed in industrial wastewaters. 28 Most of them were toxic and recalcitrant to biodegradation, causing decay in the efficiency of biological plants currently used for the treatment of wastewaters containing such coumponds. As a result, electrochemical oxidation, with strong oxidizing ability, was carried out.…”

Abstract. This paper presented a detailed chronological survey of scientific output related to electrochemical oxidation in SCI categories of "environmental sciences, environmental engineering and water resources" from 1975 to 2012. Publications were analyzed by distribution of the number of publications and times cited, source categories, source journals, author keywords, KeyWords Plus, and the most cited publications in these years. It was concluded that Pt, boron-doped diamond, TiO 2 were currently and would continue to be the predominant focused electrode materials at least over the next decade. And the foci of studied pollutants in the electrochemical oxidation were mainly concentrated in dyes and phenols popularly existing in the practical wastewaters. What's more, electrochemical degradation, wastewater treatment, electrochemical determination and fuel cell would be the key research topics currently and recently. Fenton, photocatalysis and coagulation were the most-frequent combination technology with electrochemical oxidation based on the bibliometric results. Contribution of Croatian chemists to the field is mentioned.
