Determination of Surface Heterogeneity and Enthalpies of Ca-K And Pb-K Systems in Tropical Soil Using Flow Adsorption Calorimetry
نویسنده
چکیده
Sorption reactions of Ca, Cd, and Pb dictate the extent to which these metals will be labile in the soil environment (Naidu et al., 1998). Therefore, the ability to directly monitor the energetics of sorption reactions involving these metals would provide vital information concerning the mechanisms of sorption as well as other chemical processes occurring. Flow adsorption calorimetry provides a direct and quantitative measure of the heat (enthalpy) evolved during a reaction and was used in this study to measure the energetics of reactions of Ca, Cd, and Pb occurring at the liquid/solid interface.

Competitive Adsorption of Cu, Ni, Pb, and Cd from Aqueous Solution Onto Fly Ash-Based Linde F(K) Zeolite
The reaction of fly ash with a KOH solution was used to synthesize Linde F(K) zeolite, following which Fourier transform infrared spectroscopy were used to characterize the crystalline material. The competitive adsorption of Cu, Ni, Pb, and Cd onto this zeolite was subsequently studied in quaternary solution systems. The results show that the metal removal rates gradually increase with incr...
متن کاملExperimental modeling of the adsorption kinetics of Cd (II) and Pb (II) ions by Calix [4] arene surface
The removal of Cd2+ and Pb2+ ions from wastewater using p-tert-butyl-calix[4] arene was investigated in terms of initial pH, initial concentration, adsorbent dosage, contact time and temperature. The maximum adsorption occurred at the pH value of 6. The adsorbent studied exhibits high efficiency for Cd (II)and Pb (II) adsorption and the equilibrium states could be achieved in 10 min. Adsorption...

Constructed wetlands have not been commonly used in Vietnam due to the lack of information in the selection of proper types of constructed wetlands, type of reeds, design parameters and performance efficiency, in tropical climates. This paper focuses on Canna generalis, which is a common reed and easy to grow both in water and wet land conditions. Two kinds of hybrid constructed wetlan...
متن کاملSequential sorption of lead and cadmium in three tropical soils.
It is important to examine mechanisms of Pb and Cd sorption in soils to understand their bioavailability. The ability of three tropical soils to retain Pb, Cd, and Ca was evaluated. The objectives of this study were to (1) determine the extent to which soil sorption sites are metal specific, (2) investigate the nature of reactions between metals and soil surfaces, and (3) identify how metals co...

ABSTRACT-The influence of intensive crop rotation on the distribution of potassium forms and clay mineralogy was assessed under a Mediterranean condition in the Piranshar region, northwest of Iran. For this purpose, surface soil samples in relation to six soil sub-groups from crop rotationfiled (sugar beet, wheat, pea, and barley) over five decades and the adjacent uncultivated lands were descr...
