Soil surface charge and cation exchange are important parameters of soil fertility in tropical soils. This study was conducted to investigate characteristics of surface charges and cation exchanges on four soil orders of the dryland in  Aceh Besar di... see more

The possibility of using the cation-exchange resin Lewatit K2420 as a catalyst for the synthesis of 1,3-butadiene from isopropyl alcohol and formaldehyde solution in one technological stage has been shown. The regularities of the process have been establi... see more

Soil surface charge and cation exchange are important parameters of soil fertility in tropical soils. This study was conducted to investigate characteristics of surface charges and cation exchanges on four soil orders of the dryland in  Aceh Besar di... see more

In this study, graphene Th(IV) phosphate was prepared by sol–gel precipitation method. The ion-exchange behavior of this cation-exchanger was studied by investigating properties like ion-exchange capacity for various metal ions, the effect of eluent conce... see more

The use of cation exchange in acid cycle to obtain tartrate stability of red wine was evaluated within the limits specified by the Office International de la Vigne et du Vin (OIV). Unstable red wines submitted or not to a previous cold treatment were used... see more

Treating wines with cation exchange resins allows the reduction of pH and contributes to limiting the formation of tartrate salts by exchanging cations such as potassium with hydrogen ions. This manuscript summarizes the results of a series of l... see more

The ligand exchange rate is the significant part of complex compound kinetic. The mechanism of this process may be different. In the article the ability to apply the quantum-chemical method for determination of intermediates type and ligand exchange mecha... see more

This article presents the results of experimental research on wastewater treatment from ions of heavy and non-ferrous metals by ion exchange adsorption. The object of investigation was a model solution containing ions of heavy and non-ferrous metals and p... see more

The saturation of negative charges of zeolites by specific cations to modify their physicochemical and catalytic properties has broadened the applications of zeolites. The adsorption behavior of H+ to Li+, Na+, K+, Rb+ and Cs+-saturated Linde-type A, Na-P... see more
