Adsorption of aqueous Cd2+, Pb2+, Cu2+ ions by nano-hydroxyapatite: Single- and multi-metal competitive adsorption study
nano-hydroxyapatite (nano-HAP) Cd Pb Cu competitive adsorption selectivity coefficients
2017/8/9
Being an inexpensive but efficient adsorbent, hydroxyapatite is extensively used for decontaminating wastewater and soils polluted by heavy metals. However, its solubility and grain size can affect it...
Method for Estimating Competitive Adsorption of Herbicides on Soils
atrazine competitive adsorption estimating method linuron soil
2009/3/5
The effects of mixed herbicides in soils may differ due to interactions. Since adsorption amounts and ratios change nonlinearly with herbicide concentrations, it is necessary to control the total nu...
Effect of KCl and CaCl2 as Background Electrolytes on the Competitive Adsorption of Glyphosate and Phosphate on Goethite
Adsorption Background Electrolyte Competition Glyphosate Goethite Phosphate
