Stoichiometry of Coagulation Revisited
Environmental Science & Technology, 2008The roles of particles and natural organic matter (NOM) in determining coagulant (alum) doses in potable water treatment were investigated at two pH conditions (6 and 7). The concentrations of NOM and colloidal silica particles in raw water were systematically varied separately and in combination, and the impacts of these two classes of contaminants on

Stoichiometry and food-chain dynamics
Theoretical Population Biology, 2004Traditional models of chemostat systems looking at interactions between predator, prey and nutrients have used only a single currency, such as energy or nitrogen. In reality, growth of autotrophs and heterotrophs may be limited by various elements, e.g. carbon, nitrogen, phosphorous or iron.

Stoichiometry of vulcanization with sulfur
Journal of Polymer Science, 1951Abstract In the study of vulcanization with natural rubber and other polymers of relatively high chemical unsaturation, it has always been difficult to represent the vulcanization process molecularly because of the complexity of the sulfur-polymer reactions.

Abstract The occurrence of deviations from stoichiometry of the semi-insulator compound HgI2 has been established using a very elaborate chemical analytical procedure. It was found that the molar ratio of I 2 Hg varies from 1.993 to 2.015 (±0.002).

Stoichiometry of the amalgamation reaction
Journal of Dentistry, 1977Abstract Regression analysis of previously published data has been used to illustrate paradoxical deviations from proportionality between the measured volume fractions of the phases of set dental amalgam. Possible sources of error are identified.

The objectives of this study were to examine the adsorption of coagulants on the colloids present in water and to interpret this adsorption in terms of coagulation and restabilization; and, based upon a consideration of chemical and electrostatic interactions in the destabilization of colloids, to develop a conceptual model relating optimum coagulation
