Surface Enthalpy of Boehmite
Abs t rac t -The persistence of many seemingly metastable mineral assemblages in sediments and soils is commonly attributed to their sluggish transformation to the stable-phase assemblage. Although undoubtedly kinetics plays a major role, this study shows that thermodynamic factors, particularly surface energy, significantly influence the free energy. Enthalpies of formation of boehmite samples...
متن کاملPhosphate-ion-adsorption capability of granulated boehmite fabricated using organic binder (polyethylene terephthalate).
We investigated a method for producing granulated boehmite (BE) by using an organic binder and measured its phosphate-ion-adsorption capacity. BE was granulated using polyethylene terephthalate (PET), and its structure was characterized by scanning electron microscopy and X-ray diffraction analyses. The properties of granulated BE such as specific surface area, mean pore diameter, pore volume, ...
متن کاملFluoride ion adsorption onto palm stone: Optimization through response surface methodology, isotherm, and adsorbent characteristics data
In some part of the world, groundwater source can become unsafe for drinking due to the high concentration of fluoride ions [1]. The low cost and facile-produced adsorbent like palm stone could effectively removed fluoride ions through adsorption process. In this dataset, the influence of fluoride ion concentration, solution pH, adsorbent dosage, and contact time on fluoride ion adsorption by p...
متن کاملSpectrophotometric determination of Dalacin phosphate from formulations using reduce atomic absorption of calcium ion by phosphate
A simple, sensitive and accurate method for spectrophotometric determination of Dalacinphosphatehas been established. The method is based on the reduction of atomic absorptioncalcium ion by phosphate. Because, there is a phosphate mole in every Dalacin mole structureand with measurement of phosphate, Dalacin is beyond measurement too. Therefore, the reactionbetween acidic hydrolysis products of...
متن کاملAdsorption Equilibrium and Kinetics of Lead Ion onto Synthetic Ferrihydrites
Batch experiments were conducted to study the adsorption behaviors of lead ion (Pb2+) onto ferrihydrites prepared using three different procedures which were characterized by textural analysis (BET). The adsorption removal of Pb2+ by the three ferrihydrites (called FH-1, FH-2 and FH-3, respectively) were compared, and FH-3 shows fast adsorption kinetics as well as hig...
