Carbon Black: A Good Adsorbent for Triclosan Removal from Water

Abstract

Industrial grade carbon black was pretreated and used for adsorption of triclosan (TCS) in water, and its adsorption performance was investigated by static adsorption experiments and fixed bed adsorption experiments. The effects of pH and temperature on the adsorption capacity were investigated and the adsorption performance of carbon black and activated carbon on TCS was compared. As the pH or temperature decreased, the adsorption of TCS by carbon black increased. Carbon black had a maximum adsorption capacity of 18.62 mg/g on TCS, which was somewhat lower than the activated carbon. Furthermore, the breakthrough time increased with increasing bed height, decreasing flow rate and decreasing initial TCS concentration in the fixed bed adsorption studies. The breakthrough time was 14.33 days at a bed depth of 4.2 mm, a flow rate of 2 mL/min, and an initial TCS concentration of 0.5 mg/L TCS. The model from The Bed Depth Service Time (BDST) was well-fitting.

Removal of Nadolol Using Coupled Nanomaterials Based on Titanium and Carbon

“…A higher percentage of adsorption was observed with TiO 2 -C20 than with TiO 2 -C9, which can be related to the carbon content. It is known that carbon black has a high adsorption capacity [10], which explains the higher adsorption of NAD using a photocatalyst with a higher carbon black content. Figure 2b shows the change in pH value during the adsorption of NAD in the presence of TiO 2 -C9 and TiO 2 -C20 in the dark.…”

Enhancing Uptake Capability of Green Carbon Black Recycled from Scrap Tires for Water Purification

“…Carbon black (CB) is pure elemental carbon in a powder form that is typically produced by the incomplete combustion of heavy petrochemicals under controlled conditions [1][2][3][4][5]. Given its unique physicochemical properties, CB has served as an essential filler for tires, plastics, protective materials, electronic devices, and purification systems.…”
