Sorption isotherms of (African oil bean) Pentaclethra macrophylla benth. cotyledons were determined by static gravimetric method at different temperatures, in the range from 28 and 48 oC. Equilibrium moisture content (EMC) data were analysed using various... see more

 This study presents a novel approach to evaluate water sorption and desorption isotherm modeling consisting in statistical evaluation of the fit followed by the ranking of the models. Water sorption and desorption isotherms for BRS Elis and BRS Cauê... see more

Moisture sorption isotherms are useful thermodynamic tools for determining water interactions within food systems and providing information that can assist in optimizing food processing operations such as drying, mixing, packaging and storage, as well as ... see more

Yogurt powder was produced by freeze drying and with added candied chestnut puree at ratios of 5, 10, and 20 % by weight. Moisture sorption isotherms of yogurt powder samples, plain (YP), and containing 5, 10, 20% candied chestnut puree (CCP) were determi... see more

Amine-Modified Silica (AMS) and Quaternary Amine-Modified Silica (QAMS) has been synthesized through the sol-gel process for adsorption Au(III) in aqueous solution. The aim of this work was to compare the effect of addition three methyl group of AMS to fo... see more

Activated carbon (AC) from palm empty fruit bunches has been prepared, and this material was then used to adsorb Cr(VI) from a solution. Characterization of the AC was conducted by detection of its functional groups, determination of total volatile compou... see more

Removal of copper ions from aqueous solutions on synthetic and dentine waste hydroxyapatites (HAP) was investigated in batch sorption experiments. Kinetics of sorption followed a pseudo-first order model. Steady-state data show agreement with the Sips iso... see more
