lime, which, added in even so small an amount as 0 000426 gramme to a hundred cubic centimetres of water, kills all the micro-organisms within two hours. The bacteria appear to be acted upon much more promptly than the other organic matter present. For the removal of the excess of the agent the addition of sulphite of sodium (0 000209 gm.) suffices, and an excess of this substance up to 50 per ...

The catalytic activity of four metal ions the fourth period table by D.I. Mendeleev in oxidation potassium iodide with ammonium persulfate. greatest increase reaction rate is observed presence copper sulfate, least cobalt and nickel salts

adverse outcomes of pregnancy increase among women with high density of hemoglobin. this study evaluates the effects of iron supplementation on serum copper level in pregnant women with hemoglobin higher than 13.2 g/dl. sixty two pregnant women with hemoglobin >13.2 g/dl and normal serum copper levels in their 13-18 weeks of gestation were randomized into case and control groups. from 20 th wee...

Th is article examines the status of submersible reference electrodes and presents a new design concept for submersible copper/copper sulfate (Cu/CuSO4) electrodes (CSE). In the new concept, the half-cell potential is independent of the salinity (chlorinity) of the electrolyte, the electrode is not subject to contamination, and structure-to-electrolyte voltages do not require correction to the ...

BACKGROUND Phytic acid is a strong inhibitor of iron absorption from fortified foods. In adults, this inhibitory effect can be overcome by adding ascorbic acid with the iron fortificant or by using a "protected" iron compound such as NaFeEDTA. In addition, the use of NaFeEDTA as an iron fortificant has been reported to increase zinc absorption in adult women. No information is available on iron...

This paper describes the development of a microbial fuel cell (MFC) for electricity production from cellulose that is based on mixed culture of rumen bacteria in vitro. The fibrolytic bacteria isolated from rumen fluid were used in anode compartment of MFC, which can release glucose up to 15 g/L from carboxymethyl cellulose (CMC). At the same time, the maximum power density of 100.60mWm was gen...

Background and Objective: Copper is one of the main micronutrients of body which plays a key role as a cofactor in the function of metabolic enzymes. Previous studies have shown that copper sulfate () inhibits long-term potentiation (LTP) in slices of hippocampal CA1 region. Whereas LTP is involved in learning and epilepsy, it seems that copper effects on LTP could be associated with its effect...

Copper is a metallic element that occurs naturally as the free metal, or associated with other elements in compounds that comprise various minerals. Most copper compounds occur in +1 Cu(I) and +2 Cu(II) valence states. Copper is primarily used as a metal or an alloy (e.g., brass, bronze, gun metal). Copper sulfate is used as a fungicide, algicide, and nutritional supplement. Copper particulates...
