Characterization of diatomaceous earth modified by organic ligands for enhanced zinc adsorption
(Elsevier, 2019-08)
In order to enhance zinc adsorption, natural diatomaceous earth was modified by a simple batch procedure incorporating ligands with carboxylic and amine functional groups: ethylenediaminetetraacetic acid and 2-N(hydroxyethyl) ...
Insecticidal efficacy of beauveria bassiana, diatomaceous earth and fenitrothion against rhyzopertha dominica and tribolium castaneum on stored wheat
(Taylor & Francis, 2018-07)
Bioassays were conducted in stored grains to evaluate the combined use of the entomopathogenic fungus Beauveria bassiana, diatomaceous earth (DE) and fenitrothion against adults of Rhyzopertha dominica and Tribolium ...
Phosphorus adsorption by a modified polyampholyte-diatomaceous earth material containing imidazole and carboxylic acid moieties: Batch and dynamic studies
(Royal Society of Chemistry, 2017-06)
The aim of this study was to investigate phosphorus removal in water by using a polyampholyte obtained by the reaction of methacrylic acid, ethylene glycol diglycidyl ether and imidazole by a one step synthesis, mixed with ...
