The chemical composition of precipitation at cloud levels

Quarterly Journal of the Royal Meteorological Society, 1962
AbstractIn an attempt to obtain precipitation samples free from contamination either from industrial sources or from sea spray, samples were collected by an aircraft of the Meteorological Research Flight over Southern England at heights up to 8,500 ft.

Factors affecting the chemical composition of precipitation in Syria

Environmental Science and Pollution Research, 2020
Concentrations of the major ions (Ca2+, Mg2+, Na+, K+, NH4+, Cl-, HCO3-, SO42- and NO3-), pH and electrical conductivity (EC) values in the rainwater (RW) samples at 16 stations in Syria were determined for characterizing the principal factors affecting the chemical composition of precipitation (P) in this country. Collection of the RW samples was made

Sulfide removal in petroleum refinery wastewater by chemical precipitation

Journal of Hazardous Materials, 2008
Sulfide removal by chemical precipitation from petroleum refinery wastewater was investigated. The wastewater samples were taken from the flocculation pond influent of TUPRAS Kirikkale Middle Anatolia Petroleum Refinery Wastewater Treatment Plant (WWTP) and physicochemical treatments using conventional coagulants which were partial precipitant [FeCl(3)

Chemical Waves and Periodic Precipitation Processes

1988
A nonlinear chemical reaction with sufficiently complex reaction mechanism, maintained far from equilibrium, may show the phenomenon of chemical waves or fronts which are traveling concentration gradients 1,2,3,4 Chemical waves may occur in a variety of systems, including oscillatory reactions or reactions in a stable stationary state with so-called ...

Chemical Conditions for the Precipitation of Banded Iron-Formations [PDF]

open access: possible, 1980
Of all the geological sources of evidence that have been quoted as to the composition of the atmosphere and surface waters in the Archaean and early Proterozoic, banded iron-formations (BIF) deserve special attention. Not only to they occur in vast quantities and widely distributed on the continents, not only are they virtually restricted to rocks ...
