water desorption isotherms of raw and osmotically dehydrated garlic

water desorption isotherms of raw and osmotically dehydrated (at 25ºc, for 2 hours, with 10 and 26% nacl solutions) garlic slices at different temperatures (25, 40, 55, and 70ºc) were experimentally determined over a range of water activity of 0.05–0.90 using a static gravimetric method. desorption isotherms can be classified as type iii. the water desorption isotherms of raw garlic clearly sho...

isotherms of adsorption on and desorption from calcite of boron: ph and salt dependency

the role of calcite as related to the chemical behavior of boron (b) in calcareous soils was investigated through an assessment of b adsorption and desorption reactions on and from calcite in four ratios of solid to solution rate, three levels of ionic strength, and within a ph range of 7.5 to 11.5. experimental data indicated that b adsorption is increased by an increase in the solid to soluti...

Moisture Desorption Isotherms and Isosteric Heat of Sorption Characteristics of Malting Barley (hordeum Distichum L.)

 The equilibrium moisture content of malting barley grains (cv. Scarlett) was determined by gravimetric-static method in the range 20-50°C using saturated salt solutions (LiCl, MgCl2.6H2O, K2CO3, NaBr, NaNO2, KI, NaNO3, NaCl, (NH4)2SO4) to provide water activities for each temperature between 0.11 and 0.813. Desorption isotherms were obtained at 20, 30, 40, and 50°C. All the sorption curves w...

Calculations of Pore Size Distributions in Nanoporous Materials from Adsorption and Desorption Isotherms

The recently developed density functional theory method for pore size distribution analysis from nitrogen adsorption and desorption isotherms is extended to materials with pores ranging from 2 to 100 nm. The method is based on the nonlocal density functional theory (NLDFT) of capillary condensation hysteresis in cylindrical pores. It is shown that NLDFT correctly predicts both the adsorption an...
