Periodic (Liesegang) Precipitation of Chemicals

Nature, 1963
LIESEGANG'S periodic precipitation of inorganic chemicals1 has yet to be explained adequately, possibly because experiments in gathering data to describe it have failed to recognize and control numerous complicating effects influencing it. Some of these are illustrated in the work reported here.

Copper precipitates in silicon: Precipitation, dissolution, and chemical state

Journal of Applied Physics, 2002
The precipitation and dissolution of copper impurities at oxygen precipitates and stacking faults in silicon were studied using thermal budgets commensurate with standard integrated circuit processing. Additionally, in order to develop a better understanding of the dissolution process, we have obtained results on the chemical state of the copper ...

Fundamentals of Chemical Coagulation and Precipitation

2021
Chemical treatment is considered as a useful tool for (a) pretreatment of harmful wastes, (b) early removal of undissolved precipitating substances, (c) reduction of load fluctuations, (d) combating bulking activated sludge, (e) polishing effluents, and (f) phosphorus removal. Chemical treatment as a rule means addition of chemicals. Such chemicals are

The Chemical Composition of Precipitation in Madrid

Water, Air, and Soil Pollution, 2003
The present study examines the chemical characteristics of first-fraction precipitation samples collected over a period of one year in Madrid, and patterns of temporal and spatial variation observed in their composition. One hundred and sixty-four samples of wet precipitation collected on an event basis were analysed for anions, cations, pH and ...
