The Determination of Inorganic Sulphate in Sodium Lauryl Sulphate

open access: yesJournal of Pharmacy and Pharmacology, 1959
Abstract The official method for the determination of inorganic sulphate in sodium lauryl sulphate is time-consuming. Separation of organic and inorganic sulphate via the lead salts followed by complexometry leads to a rapid and convenient method with readily reproducible results.

Low waste technology for mine waters treatment using lime and aluminum coagulants

open access: yesChemistry Journal of Moldova: General, Industrial and Ecological Chemistry, 2023
In this paper the process of reagent desalination of mineralized mine waters was studied. The peculiarity of mine waters in many regions of Ukraine is that, along with hardness ions, they also contain sulphates in fairly high concentrations.

The sulphation of chondroitin sulphate in embryonic chicken cartilage [PDF]

open access: yesBiochemical Journal, 1969
1. Whole tissue preparations and subcellular fractions from embryonic chicken cartilage were used to measure the rate of incorporation of inorganic sulphate into chondroitin sulphate in vitro. 2. In cartilage from 14-day-old embryos, [35S]sulphate is incorporated to an equal extent into chondroitin 4-sulphate and chondroitin 6-sulphate at a rate of 1 ...

The availability of inorganic sulphate in blood for sulphate conjugation of drugs in rat liver in vivo. (35S)Sulphate incorporation into harmol sulphate [PDF]

open access: yesBiochemical Journal, 1978
1. When Na235SO4 is injected intravenously in rats, it is immediately available for sulphate conjugation of the phenolic drug harmol (7-hydroxyl-1-methyl-9H-pyrido[3,4-b]indole) in the liver. This was established by following the time course of the biliary excretion of the sulphate conjugate of harmol, and the incorporation of [35S]sulphate into harmol
