Removal of high concentration phenol from aqueous solutions by electrochemical technique

Abstract

In this study, the ability of the electrochemical process to remove aqueous high concentration phenol using an electrochemical cell with aluminum anode and cathode was examined. The removal rate of phenol was monitored using different parameters phenol concentration, pH, electrolysis time, current density, and electrode distance. Obtained results indicated that the low removal rates of phenol were observed at both low and high pH. However, the removal rate of phenol increased with an increase in the current density, each electrochemical process conditions need a certain electrodes distance. removal rate of phenol decreased with the increase in the initial phenol concentration. The maximum removal rate of phenol obtained from this study was 82%.

“…The Freundlich isotherm model were discovered to be favorable for biochar prepared from Wheat husks. [1,2,[11][12][13][14][15][16][17][18][19][20]3,[21][22][23][24][25][27][28][29][30][31]4,[32][33][34][35][36][37][38][39][40][41]5,42,[6][7][8][9][10]…”

A Review About Preparation and Properties of Biochar and Application Fields in the Environment

“…and safer in comparison with other types of charcoal when turning carbon to stable form. As a material which is environmentally friendly and low-cost.From the literature, adsorbents were prepared from environmentally friendly materials, such as [5] prepared pillared clay as an adsorbent from Iraqi clays, [6] prepared the adsorbent from tea leaves, while, [7] prepared adsorbent from a waste of tea. Figure (1) shows pyrolysis as a combustion stage [4].…”

“…Biochar primarily promoted the production of macro-aggregates, which has been more pronounced in clayey soil supplemented with manure-based low-temperature-biochar [61]. The relation between biochar, organic material, and soil is illustrated in Figure (7).…”

Synthesis, Characterization, and Application of Ag-Biochar Composite for Sono-Adsorption of Phenol

“…Phenolic compounds are categorized as one of the most hazardous compounds in the environment (Hejazi et al, 2019;Mojoudi et al, 2019;Pantić et al, 2021), and phenol is chosen as the model pollutant in this study because it has been listed as a priority pollutant due to its toxicity and hard biodegradability once it is discharged into the natural environment. The high toxicity and low biodegradability of phenol pose a severe threat to the environment, even in low concentrations (Alnasrawy et al, 2021). Phenol and its derivative compounds may cause blindness, liver and pancreas damage, kidney failure, dark urine, paralysis, nervous disorder, and cancer (Parada Jr et al, 2019;Thang et al, 2019).…”
