In this study adsorption of 1-chloro-4-nitrobenzene (CNB) from aqueous solutions onto multi-walled carbon nanotubes (MWCNTs) was surveyed. The effect of some key parameters such as pH (2-10), carbon nanotubes dosage (0.02-0.1 mg/250mL), CNB concentration (2- 16 mg/L), and temperature (20,30,40,50°C) were investigated. The results showed that, the variation of initial pH and CNB concentration ex...

Background: Synthetic dyes have several harmful effects on human health as well as aquatic life. In this study, activated carbon (AV-AC), based on Aloe vera leaf shells, was used as a novel agricultural adsorbent, one that is low-cost and available for the removal of Congo red (CR) as a carcinogenic dye from aqueous solutions. Methods: In the batch system, the influence of different paramete...

Background & objectives: Dyes are structurally complex materials, which enter into the environment due to discharging of textiles effluent from dyeing and printing processes. Reactive Blue 52 dye is used widely in the textile industry. Therefore, we investigated the efficiency of the filamentous Alga as natural adsorbent in the removal of Reactive Blue 52 dye from textile wastewater. Methods: ...

Introduction: Di (2-ethylhexyl) phthalate is one of the most abundant phthalate esters and it is widely used as softeners in plastic products. Malformation, carcinogenicity, the poisoning of the reproductive system, and also the disruption of the human endocrine system are the harmful effects of these substances. Materials and Methods: In this research, the removal of di (2-ethylhexyl) phthal...

biosorption of acidic dyes using the live fern azolla filliculoides was studied in a discontinuous system. dye parameters, dye initial concentration and contact time were studied in temperature range of 25-30 ?c and ph=7. it was shown that increasing the 23initial concentration of dye and its contact time resulted in decreasing the dye taking quantity by the absorbent. also, type of dye has an ...

In the current investigation a novel nano hybrid adsorbent MCM-41/N-(3-trimethoxysilyl)-propyl)diethylenetriamine (MCM-41/TMSPDETA) was prepared and was characterized using DLS (Dynamic Light Scattering), Fourier Transform Infrared (FTIR), X-ray diffraction (XRD), Brunauer–Emmett–Teller (BET) analytical techniques and Transmission electron microscopy (TEM). The synthesized MCM-41/TMSPDETA adsor...

The present study seeks to investigate the capacity of polyaniline/titanium dioxide (PAn/TiO2) and Polypyrrole/titanium dioxide (PPy/TiO2) nano-adsorbents to adsorb Congo red anionic dye (CR) from aqueous solution. The variables effective in CR adsorption, including adsorbent dose, pH of the solution, contact time, initial dye concentration, and temperature were examined. The study yielded the ...
