In situ modification of activated carbons developed from a native invasive wood on removal of trace toxic metals from wastewater

Development and Environmental Applications of Activated Carbon Cloths

“…The trend agrees with results reported for the adsorption of different metal ions on conventional activated carbons and on some commercial ACC [7,63,114]. Total acidity of carbon sorbents is important in relation to their potentiality for liquid-phase adsorption of inorganic and organic polar molecules, particularly for wastewater treatment [2,4,[6][7][8]. The results highlighted the relevance of acidic oxygen surface groups on the denimbased ACC in connection with their behavior as cationic exchangers, in line with results for conventional activated carbons.…”

“…The discharge of effluents containing pollutants generated from different anthropogenic activities, such as heavy metals, nitrates, phosphates, into water courses constitutes a serious environmental problem which affects water quality. It is well recognized that concentrations of these species above the admissible threshold in aquatic environments cause harmful effects on humans and a variety of other living species because of their toxicity, persistence, and accumulation in living tissues throughout the food chain [7,12]. Heavy and/or toxic metals are present in raw wastewater streams from several industries such as plating plants, batteries, welding, and alloys manufacturing, nonferrous metals mineral processing, dye industries, porcelain enameling, and steamelectric power plants [114][115][116][117].…”

“…Activated carbon in powdered and granular forms is a wellknown, versatile adsorbent of widespread use in a broad spectrum of applications, including purification, remediation of polluted aquatic environments, treatment of liquid and gaseous effluents generated in industry, gas storage and delivery, metal recovery, catalysis, and biomedical applications, among various others [1][2][3][4][5][6][7][8][9][10][11][12]. Growing concern and stricter regulations pertaining to environmental pollution have led to the increase of the activated carbon demand, which is forecasted to continue raising in the near future [13,14].…”

“…Z-10A'ya boyar madde adsorpsiyonu ile 453-960 cm -1 dalga sayısı aralığında yer alan piklerin şiddetinde azalma meydana gelirken, 1433 cm -1 dalga sayısında yeni bir pik oluşumu gözlenmiştir. Oluşan bu yeni pikin boyar madde yapısında bulunan N-N ve N=N gruplarından kaynaklandığı sonucuna varılmıştır [23,29,30].…”

Feasible pretreatment of textile wastewater for dark fermentative hydrogen production

“…There are many articles that highlight activated carbon as an adsorbent to treat wastewater. Celis et al [7], Huang and Su [8], El-Sikaily et al [9] and Suzuki [10] used AC to remove toxic metal. Temmink and Grolle used AC to remove cationic and color related compounds [11].…”
