Two cases of hydrazine hydrate dermatitis without systemic intoxication.
Hydrazine hydrate is an irritant which readily vaporizes. The irritant effects are not immediately noticeable. They develop gradually over several hours (Byrkit and Michalek, 1950). The local effects are inflammation of the skin and of the mucous membranes of the upper respiratory tract and eyes. Krop (1954) reports the occurrence of hydrazine dermatitis. Individual susceptibility to dermatitis...
متن کاملthe influence of hydrazine hydrate in the preparation of lead sulfide thin film
in this paper a chemical deposition procedure for the preparation of lead sulfide thin film ispresented. the details of the preparation method are described. the influence of hydrazine hydrate onthe microstructure and deposition rate of lead sulfide thin film has been investigated. the concentrationof the lead ions in the deposition bath decreases more slowly when the hydrazine hydrate is added...
متن کاملSynthesis of Graphene Oxide using Modified Hummer’s Method and its Reduction using Hydrazine Hydrate
Graphene is a hot area of research because of its unique and remarkable properties. These properties have invoked researchers to use this form of carbon in various potential applications. One of the bottlenecks in developing such application is mass production of graphene. Hummer’s Method is one of the easiest and economical methods to synthesize huge amount of reduced graphene oxide (RGO) shee...
متن کاملFacile Synthesis of ZnO Nanorods by Microwave Irradiation of Zinc–Hydrazine Hydrate Complex
ZnO nanorods have been successfully synthesized by a simple microwave-assisted solution phase approach. Hydrazine hydrate has been used as a mineralizer instead of sodium hydroxide. XRD and FESEM have been used to characterize the product. The FESEM images show that the diameter of the nanorods fall in the range of about 25–75 nm and length in the range of 500–1,500 nm with an aspect ratio of a...
متن کاملMutation Breeding of Lipase-producing Strain Flavobacterium sp. by Supercritical CO2 with Hydrazine Hydrate
This work aimed to obtain an ideal mutant strain with higher lipase yield using hydrazine hydrate (HZH) as a novel additive to treat Flavobacterium sp. strain YY25 by supercritical CO2. The survival rate and the positive mutation rate of the tested strain were strongly dependent on the dose of HZH. The treatment by 0.5% HZH in supercritical CO2 (8 MPa, 35°C) for 30 min provided 58.3% of positiv...
