Self-Organization Processes in Aqueous Solution of Polyvinyl Alcohol, L-Cysteine, and Silver Nitrate

Процессы самоорганизации в водном растворе L-цистеина, нитрата серебра, карбоксиметилцеллюлозы (КМЦ) и сульфата натрия исследованы с использованием методов вискозиметрии и УФ спектроскопии. Установлено, что водный раствор на основе L-цистеина и нитрата серебра (цистеин-серебряный раствор - ЦСР) хорошо совместим с водным раствором КМЦ, образуя при этом прозрачный гидрогель без введения электролита-инициатора. Рост концентрации КМЦ в растворе и дополнительное введение электролита (сульфат натрия) приводило к увеличению вязкости получаемых гидрогелей. Self-organization processes in an aqueous solution of L-cysteine, silver nitrate, carboxymethyl cellulose (CMC), and sodium sulfate were studied using viscometry and UV spectroscopy methods. It was found that an aqueous solution based on L-cysteine and silver nitrate (cysteine-silver solution - CSS) is well compatible with an aqueous solution of CMC, thus forming a transparent hydrogel without introducing an initiator electrolyte. An increase in the concentration of CMC in solution and an additional introduction of an electrolyte (sodium sulfate) led to an increase in the viscosity of the resulting hydrogels.

Mercury Poisoning

Polyvinyl alcohol preservative (PVA) is used routinely in the laboratory for collection of specimens for examination for ova and parasites.1-4 PVA, presently used at Harbor-UCLA Medical Center, contains: 4.5% mercuric chloride, 5% polyvinyl alcohol, 30% denatured alcohol, 4.5% acetic acid, and 1.5% glycerin in an aqueous solution. The kit, as shown in the Figure, contains three bottles with 10-ml aliquots of PVA, wooden sticks for mixing the specimen, and written instructions for collection of the specimens. The bottles are clearly labeled as poison in English and Spanish, and specific verbal as well as written instructions are given to patients and their families when the ova and parasite kits are dispensed.
