Adsorption is a widely used technique for the treatment of wastewater containing dyes, which are pollutants that can have serious impacts on aquatic ecosystems. In this work, activated carbon (AC) was prepared from cashew nut shell (CNS) and to adsorb methylene blue (MB) solution. The CNS AC characterized by scanning electron microscopy, Fourier transform infrared spectroscopy, nitrogen adsorpt...

Neste estudo, a biossorção do corante Rodamina B (RhB) de solução aquosa usando mesocarpo coco babaçu (BCM) foi avaliada em batelada e operação contínua. As influências pH, tempo contato, concentração biossorvente, temperatura foram investigadas estudos batelada. Taxas mais altas remoção RhB (79,3 ± 0,49 %) obtidas pH 2.0. Os cinéticos equilíbrio indicaram que segue o modelo pseudossegunda orde...

Two easily accessible local materials, kaolin, and sediments from the reservoir of a dam, were evaluated to compare their efficiencies as adsorbents for As. The kaolin sample was composed mainly by kaolinite quartz, while contained illite, montmorrillonite quartz. Also, iron, calcium magnesium minerals present minor components. adsorption experiments performed using batch equilibrium techniques...

The study aim was to test the applicability of exoskeletons and molts from mealworm (Tenebrio molitor) cultures as sorbents for anionic dyes: Reactive Black 5 (RB5) Yellow (RY84). Factors investigated included: characteristics (FTIR, pHPZC), influence pH on sorption efficiency, kinetics (pseudo-first, pseudo-second-order, intraparticle diffusion models), determination maximum capacity (Langmuir...

This study deals with the removal of single and binary heavy metals, which cause great problems in terms environment human health, through very low cost, economical easily obtainable materials. The purpose this is to investigate single- uptake Copper (II) Nickel ions onto Sepiolite a thermodynamic perspective. For mono-component systems, initial effluent concentration, mixing speed temperature ...

Journal: :C 2023

In this study, activated carbons derived from walnut shells (CA-N) and apple wood (CA-M) were used as adsorbents to remove cobalt(II) strontium(II) ions aqueous solutions. The novel materials obtained using nitric acid (CA-Mox) acid/urea mixture (CA-Mox-u, CA-Nox-u) oxidizing agents. physical–chemical characteristics of determined nitrogen sorption isotherms, SEM-EDX, FTIR, pH metric titrations...

The heat accumulated in the inner parts of earth's crust is transmitted to fluid geothermal aquifer by means transportation. transported surface either wells or naturally. In this study, Tuzla field Çanakkale city was examined due its high boron content (10.3 mg L-1). It aimed remove from adsorption order prevent possible negative effects on environment. Fly ash obtained Çan thermal power plant...
