A highly selective and sensitive direct detection of potassium (K+) and lead (Pb2+) ions was developed by using the assembly and disassembly of a chiral cyanine dye/TBA complex. The dye DMSB (3-ethyl-2-[3-(3-ethyl-3H-benzoselenazol-2-ylidene)-2-methylprop-1-enyl] benzoselenazolium ...
Early studies on the antifungal efficacy of potassium peroxymonosulfate did not reveal good efficacy; however, in those studies, the contact time was less than 5 minutes, and the spore-to-disinfectant challenge was robust.21 In subsequent studies, this product was found to be antifungal ...
the sodium salt is maintained in 8% to 10% and then subject to calcination at 900~1000 ℃ to obtain the black ash. The black ash is pulverized and subject to hot water extraction. The immersion is further subject to evaporation to precipitate some part of unconverted potassium sulfate out;...

Sodiumchloride(with a final concentration of 0.2 M) is used if the DNA solution containssodium dodecyl sulfate(SDS), because this remains soluble in 70% ethanol and disappears with the supernatant. Ammonium acetate(with a final concentration of 2 to 2.5 M) is used if the solution contains nuc...
It is utilized for the precipitation of dodecyl sulfate bound proteins, thereby removal of proteins from DNA. It plays an important role in preserving tissues, fixation and mummification. 8.1 Usage Potassium Acetate is a potassium salt employed to replenish electrolytes, for restoration of water-...

Potassium hydroxide is a raw material in the production of various K salts, mainly K carbonates, and also citrates, silicates, acetates, etc. Potassium carbonate confers excellent clarity to glass thus is used for most fine optical lenses, eyeglasses, fine crystal, glassware, chinaware and TV...
On treating with cesium fluoride in diglyme or acetonitrile, the perfluorinated cyclic sulfate (96) underwent an exothermic fragmentation to trifluoro-2-oxopropionyl fluoride (139) and sulfuryl fluoride, presumably via initial attack at sulfur by fluoride ion 〈73IZV2725〉.
