The adsorption of CO on the supported gold nanoparticle catalysts Au/TiO2, Au/Fe2O3, and Au/ZrO2 was examined using infrared transmission spectroscopy to quantify the isobaric CO coverage as a function of temperature. The Temkin adsorbate interaction model was then applied to account for the adsorption behavior. To test the general applicability of the Temkin model, this treatment was also appl...

background and purpose: today, by increasing different pollutants, the continuous monitoring of surface waters is essential. dorudzan dam is one of the main sources of surface water in fars province, iran; hence, the current study investigated the quality  of dorudzan reservoir for drinking and irrigation consumptions. materials and methods: in this study, various physicochemical parameters [ph...

Background and Purpose: Phenol and derivatives are common pollutants of drinking water which are blamed for crucial adverse effects such as poisoning, cancer, and malformation. In this study, an activated carbon of Miswak’s root (MR) was used for the removal of phenol from aqueous solutions as a low-cost and high surface adsorbent. Materials and Methods: Adsorption exper...

Abstract The CO 2 calcium based adsorbent was prepared by using citric acid monohydrate, L(+)-tartaric acid, glacial acetic and L(-)-malic modified eggshell. cyclic calcination/carbonation reaction of the before after modification carried out thermogravimetric analyzer to investigate attenuation characteristics absorption performance calcium-based modification. XRD, N adsorption analysis other ...

PURPOSE To determine changes in physicochemical surface properties of contact lenses (CLs) during daily wear and effects of lens wear on adhesion of a Pseudomonas aeruginosa strain from a patient with CL-related keratitis. METHODS Ten new CL wearers used ionic, etafilcon A lenses with 58% water on both eyes for approximately 10 hours each day during 10 and 50 days. All lenses were treated dai...

The efficiency of chemoinformatics methods based on a fragment approach for the analysis relationships between chemical structure textile dyes and colour fastness dyeings have been shown by examining large set properties, including light acid wool polyamide fibres, sensitivity to oxygen bleaching, wash wool, adsorption direct cotton, photodegradation azo in solution. An developed regression mod...

This paper presents the results of Pb2+ adsorption from synthetic Pb(NO3)2 solutions, using beech sawdust and wheat straw as adsorbents. Physicochemical characterization adsorbents included specific surface area, pHpzc, SEM-EDS FTIR analysis. Adsorption kinetics isotherms, well changes in pH solution during process, were monitored analyzed. The showed that is explained by pseudosecond order kin...

A new modified magnetic Graphene Oxide with Chitosan and Cysteine wassynthesized for removing Pb2+ ions from aqueous solution. The properties of thisadsorbent were characterized by Field Emission Scanning Electron Microscopy (FESEM),Vibrating Sample Magnetometer (VSM) and Energy Dispersive Analysis Systemof X-ray (EDAX). Physicochemical parameters such as effect of pH, c...
