The purification of 18O-water [PDF]

open access: yesAustralian Journal of Chemistry, 1959
A reliable method for the purification of 15 to 20 mg samples of 18O-water, as a preliminary step to the measurement of isotopic composition by a density technique, is described. The method is based on the use of copper oxide as the oxidizing agent but negligible isotopic dilution is involved as the oxygen of the oxide is obtained by electrolysing a ...

Investigation of Microbiological Quality Changes of Roof-Harvested Rainwater Stored in the Tanks

open access: yesResources, 2021
Rainwater has been found to be a valuable source of drinking water in Europe, especially in such crisis situations as those caused by contamination of water uptake into water supply systems, large-scale floods or terrorist attacks (e.g., biological ...

Enhanced coagulation of covalent composite coagulant with potassium permanganate oxidation for algae laden water treatment: Algae and extracellular organic matter removal

open access: yesChemical Engineering Journal Advances, 2023
The enhanced coagulation performance for algae and extracellular organic matter (EOM) removal by using novel Al/Fe-based covalently bonded composite coagulants (CAFM) coupled with potassium permanganate oxidation was evaluated in the current study.

Lime-Phosphorus Fertilizer Efficiently Reduces the Cd Content of Rice: Physicochemical Property and Biological Community Structure in Cd-Polluted Paddy Soil

open access: yesFrontiers in Microbiology, 2021
Due to the biomagnifying effect in the food chains, heavy metals will cause serious harm to the food produced in paddy soil, and then threaten human health. The remediation of soil heavy metals by the addition of amendments is a common method.

Binding of Cd(II) by Amorphous Aluminum Hydroxide-Organophosphorus Coprecipitates: From Macroscopic to Microscopic Investigation

open access: yesAdsorption Science & Technology, 2021
The mobility of Cd(II) in soils, sediments, and aquatic systems is strongly dependent on adsorption behaviors occurring at the mineral-water interface, and this process may be influenced by the presence of organic phosphorus (OP).

Purification of Water by Infusoria [PDF]

open access: yesEpidemiology and Infection, 1911
Infusoria have the same bactericidal power as flagellates. Emulsions containing Bacillus typhosus, Vibrio cholerae, V. Dunbar, V. El Tor, B. megatherium and Spirillum volutans, to which Colpoda cucullus is added, are soon cleared. Before the clearage the Colpodae multiply actively.This bactericidal effect does not depend upon the production of toxic ...

Water Purification in Atmospheric Water Generator [PDF]

open access: yesPort Said Engineering Research Journal, 2022
Atmospheric Water Generator (AWG) is a machine that could save the Earth from running out of fresh water in the future. This machine extracts clean water from humid air using power source to decrease the air temperature to its dew point.
