The results of the study indicated that potassium dichromate was cytotoxic to HepG2 cells. The LD50 values of ± µg/ml, ± µg/ml, respectively, for cell mortality at 24 and 48 hrs were observed, indicating a dose and timedependent response with regard to the cytotoxic effects of potassium dichromate.
In the present investigation, the oxidizing roasting process of chromite with sodium carbonate to prepare potassium dichromate crystals was studied in the microwave field with air, by heating the chromite and sodium carbonate. The chromite and sodium carbonate heated separately at 1000 °C in the microwave oven (frequency: GHz; power kW) in order to study the microwave absorption ...

Steven V. Ley, Andrew Madin, in Comprehensive Organic Synthesis, 1991. In Aqueous Sulfuric Acid. Sodium dichromate in aqueous sulfuric acid has been used since the turn of the century. 6 It is a very strong oxidant; the use of this system to oxidize primary alcohols is severely limited by overoxidation, via the aldehyde hydrate, to the corresponding acid.

Potassium dichromate in acidic medium is a strong oxidative agent (chromic acid) that reacts with reducing substances present in soil. This is the Walkley‐Black wet digestion method for the ...
Less dichromate was sorbed than the other two ions and wa similar in both surface and subsurface horizons for each soil. Dichromate sorption increased with decreasing pH. Arsenate sorption from solutions containing all three ions was not greatly different to influenced by changes in soil solution pH.

Fish are highly perishable. A central concern of fish processing is to prevent fish from deteriorating, and this remains an underlying concern during other processing operations. Fish processing can be subdivided into fish handling, which is the preliminary processing of raw fish, and the manufacture of .
