چکیده
Adsorption of metal ions and dyes from water by cashew nut testa tannin resin (CATAR) was studied the effects temperature, initial pH, concentration time were investigated. Scanning electron microscopy (SEM) infrared spectroscopy (FTIR) reveal effective adsorption processes. Kinetic studies show that CATAR is complex thermodynamic parameters calculated spontaneous endothermic pollutants onto CATAR. The use as an alternative adsorbent proposed considering simulated wastewaters gave excellent removal performances 94.0% (Cd ions), 99.4% (Cu ions) 97.1% (Pb at pH 6 303 K using amount Removal obtained for dye similar conditions 71.1%, 79.2% 86.6%, respectively crystal violet, methylene blue malachite green.

Cashew Nut Testa Tannin: Assessing its Effects on the Corrosion of Aluminium in HCl
Cashew nut testa tannin [CASTAN] has been found to inhibit the corrosion of aluminium in hydrochloric acid solutions using gravimetric, thermometric and UV/visible spectrophotometric techniques. CASTAN inhibition was by adsorption on aluminium following Temkin isotherm in 0.1 M HCl and Langmuir isotherm in 0.5 M and 2.0 M HCl at 303 Kelvin. Physical adsorption on aluminium has been proposed in ...

Preparation and Characterization of Modifed PEEK-WC: DEHPA Microspheres for Rhodamine B Adsorption. Kinetics Studies
Functionalized polymeric microspheres based on a modifed polyether ether keetone (PEEK-WC) using immersion precipitation techniques were successfully prepared by doping initial polymeric solutions with DEHPA. The viscosity of the doping solution was measured for determining the optimal value for obtaining reproducible capsules. The modifed microspheres were characterize...
متن کاملThermal study of phenol-formaldehyde resin modified with cashew nut shell liquid
In this study, an experimental phenol–formaldehyde resin with 20% phenol replacement by cashew nut shell liquid (CNSL) was studied and compared with a conventional phenol–formaldehyde resin synthesized totally from petrochemical rawmaterials. The resins were characterizedwith standard lab analysis for their physicochemical specifications, while their thermal properties were studied with thermog...
