Diesel soot coated non-woven fabric for oil-water separation and adsorption applications

Abstract

The diesel soot (DS) coated non-woven fabric was studied for oil-water separation along with the adsorption of dyes, detergents, and pharmaceuticals. The DS coated non-woven fabric showed more than 95% separation efficiency and consistent repeatable performance during oil-water separation experiment. In addition to this, the DS coated non-woven fabric of 17.2 cm 2 area successfully adsorbed ~85%, 97%, and 100% methylene blue (MB) dye, ciprofloxacin, and detergent, respectively from their respective solutions within 30 min, which was not possible using uncoated non-woven fabric. The DS coated non-woven fabric was found to be hydrophobic with the contact angle of 140° which was almost invariant upto 60 °C. Hence, the DS coated non-woven fabric showed promising performance in the oil-water separation and adsorption applications.

Design and Evaluation of a New Natural Multi-Layered Biopolymeric Adsorbent System-Based Chitosan/Cellulosic Nonwoven Material for the Biosorption of Industrial Textile Effluents

“…Figure 9b showed the variation of the adsorption capacity as a function of the temperature for a dye concentration of 600 mg L −1 and a contact time of 120 min. The variation in adsorption capacity showed the same trend for the three varied temperatures (22,40, and 60 • C). The recorded decrease in adsorption performance with the gradual increase in temperature revealed that the interaction between the PEM adsorbent and the reactive anionic dye was exothermic.…”

“…We could cite the diesel soot coated non-woven one studied for oil-water separation, along with the adsorption of dyes, detergents, and pharmaceuticals. However, the adsorption results were limited due to the hydrophobicity of the functionalized fabrics [22]. Other alternatives have been studied investigating the use of treated synthetic fabrics as adsorbents.…”

Expedited Transition in the Wettability Response of Metal Meshes Structured by Femtosecond Laser Pulses for Oil-Water Separation

“…Similarly TiO 2 (Li J. et al, 2016 ; Bano et al, 2018 ) and ZnO (Feng et al, 2015 ) nanoparticles, with extreme wettability behavior, have been employed for oil-water separation. Moreover, techniques like sol-gel, electrodeposition, chemical etching, spray and dip coating of filter paper (Du et al, 2014 ), meshes (Zulfiqar et al, 2018 ), fabric (Sharma et al, 2019 ), and magnetic sponges (Wu et al, 2015 ; Beshkar et al, 2017 ) featuring super-wetting characteristics were employed to separate oil-water mixtures. Although these techniques can separate oil-water mixtures, they consume harmful complex chemicals, and they lack durability and longevity since they are prone to mechanical damaging of the coated layers, which deteriorates their performance.…”

Candle soot-coated egg carton material for oil water separation and detergent adsorption

“…Detergent content of water can also be measured by other techniques. In one of the recent studies, diesel soot-coated fabric was studied for oil-water separation, absorption of detergents, dyes and in pharmaceuticals [33]. Phenolphthalein was added initially in detergent water which turned pink and became colourless showing the adsorption of detergents using diesel soot.…”
