“…We observed this for both argon and nitrogen, and this is in agreement with the calorimetric measurements [4,25], and a number of our computer simulation studies [8,26,27]. The heat spike observed is lower than the calorimetric heat measured by Rouquerol and co-workers [4,25], and this is because our isosteric heat was calculated using the 77 K and 87 K isotherms, and therefore our heat curve corresponds to a temperature between these temperatures.…”

“…Instead of the isosteric heat, they have suggested using the integral molecular enthalpy as an alternative to describe the adsorption enthalpy change under supercritical conditions. By starting with the differential enthalpy change of the system with pressure, oH Tot /oP [17]: [39], and the filled-circles denote the experiment data for argon adsorption on a flat surface [1]. The vertical broken line corresponds to a statistical monolayer.…”

Neutral starch microspheres (NSMs) were synthesized with epichlorohydrin as the cross-linking agent from soluble starch by inverse microemulsion method. Anionic starch microspheres (ASMs) were prepared from NSMs by the secondary polymerization with chloroacetic acid as the anionic etherifying agent. Scanning electron microscopy (SEM) revealed that microspheres had good sphericity and fine dispersibility, and the average particle size was about 75 μm. The adsorption procedure of Cu 2+ , Pb 2+ on ASMs was carried out by batch experiments, Langmuir and Freundlich adsorption models were applied to describe the experimental isotherms, the adsorption equilibrium data were found to fit the Langmuir and Freundlich isotherm model, the Freundlich isotherm was more adequate than the Langmuir isotherm in simulating the adsorption isotherm of Cu 2+ ,the adsorption of Cu 2+ , Pb 2+ on ASMs was a spontaneous, the isosteric heat of adsorption at different adsorption levels was always negative and indicative of an exothermic process. The pseudo first-and second-order kinetic models were used to describe the kinetic data, and the rate constants were evaluated. The experimental data fitted well to the second-order kinetic model, which indicated that the chemical sorption was the rate-limiting step, instead of mass transfer.
