A process to apply zinc pyrithione to cotton with washable results was patented in the United States in 1984. [12] Zinc pyrithione is used to prevent microbe growth in polyester. [13] Textiles with applied zinc pyrithione protect against odor-causing microorganisms. Export of antimicrobial textiles reached US$497.4 million in 2015. [14]
Zinc nitrate has no large scale application but is used on a laboratory scale for the synthesis of coordination polymers. [4] Its controlled decomposition to zinc oxide has also been used for the generation of various ZnO based structures, including nanowires. [5] It can be used as a mordant in dyeing.
Zinc phosphide (Zn 3 P 2) is an inorganic chemical compound.It is a grey solid, although commercial samples are often dark or even black. It is used as a rodenticide. [5] Zn 3 P 2 is a II-V semiconductor with a direct band gap of 1.5 eV [6] and may have applications in photovoltaic cells. [7]
In cases with complex or unknown matrices, the standard addition method can be used. [3] In this technique, the response of the sample is measured and recorded, for example, using an electrode selective for the analyte. Then, a small volume of standard solution is added and the response is measured again. Ideally, the standard addition should ...
Zinc oxide, ZnO, is the most important manufactured compound of zinc, with a wide variety of uses. [2] It crystallizes with the Wurtzite structure. It is amphoteric, dissolving in acids to give the aqueous Zn 2+ ion and in alkali to give the zincate (a.k.a. tetrahydroxozincate) ion, [Zn(OH) 4] 2−. Zinc hydroxide, Zn(OH) 2 is also amphoteric.
Zinc has found many uses in catalysis in organic synthesis including enantioselective synthesis, being a cheap and readily available alternative to precious metal complexes. Quantitative results (yield and enantiomeric excess) obtained with chiral zinc catalysts can be comparable to those achieved with palladium, ruthenium, iridium and others ...
Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...
Use of mass spectrometry as a second component of an operando experiment allows for optical spectra to be obtained before obtaining a mass spectrum of the analytes. [22] Electrospray ionization allows a wider range of substances to be analysed than other ionization methods, due to its ability to ionize samples without thermal degradation.
