Potassium dichromate-sulfuric acid

A closed bottle of unused potassium dichromate-sulfuric acid mixture exploded after several months in storage [1]. Previous similar incidents were summarised, and the possibility of the bottle having burst from internal pressure of carbon dioxide arising from trace contamination by carbon compounds was advanced [1,2], Two further reports of incidents within 1 or 2 days of preparation of...

Dining glass cleaning operations, acetone splashed into a beaker used previously to contain potassium dichromate-sulfuric acid mixture and the solvent ignited. Alcohols behave similarly. [Pg.1478]

Oxidation with potassium dichromate/sulfuric acid achieved more than 99% destruction of all the PAH tested, and nonmutagenic residues were obtained. Despite the good reproducibility obtained during the collaborative study, the method was discarded for the reasons outlined in Section 3.1. [Pg.52]

In its simplest form, a breath alcohol screening test consists of a sealed glass tube containing a potassium dichromate-sulfuric acid reagent impregnated on silica gel. To administer the test, the ends of the tube are broken off, a mouthpiece is fitted to one end, and the other end is inserted into the neck of a plastic bag. The person being tested then blows into the mouthpiece until the plastic bag is inflated. [Pg.260]

Feldman [23,31] digested solid samples with potassium dichromate, nitric acid, perchloric and sulfuric acid. Bishop et al. [25,32] used aqua regia and potassium permanganate for digestion. Jacobs and Keeney [33] oxidised sediments using aqua regia, potassium permanganate and potassium persulfate. [Pg.149]

Highly dangerous explodes with shock or heating to 297°C. Various materials can reduce the explosive temperature red lead -(to 192°C), sodium carbonate (to 218°C), potassium hydroxide (to 192°C). Mixtures with sodium dichromate + sulfuric acid may... [Pg.1393]
