Silver nanoparticles have proved to possess significant antibacterial properties. Nanosilver produced by electrochemical reduction stabilized by cellulose derivatives, has been evaluated by European standards (CEN TC 216) in order to find out whether they could be applied in food, industrial, domestic and institutional areas as a suitable disinfectant. Moreover, bactericidal activity of nanosil...

benzalkonium chloride is a quaternary ammounium compounds derivative under different names such as afxhang, hamoon, mahan etc, which have great and expanded use in sanitation and medical affairs. bactericidal activity of these disinfectants was fulfilled according to national standard method no.2842 on staph. aureus, sal. typhimouium and e. coli. this laboratory test showed that, except mahan t...

A total of 221 patients were evaluated to be humidifier disinfectant associated with lung injury (HDLI) through two rounds of programs through April 2015. The humidifier disinfectant (HD) brands most often associated with HDLI were found to be Oxy (n=151, 68 %) and Cefu (n=26, 17 %). Polyhexamethylene guanidine used for disinfectant for four types of HD brands including Oxy was found to be asso...

With the fast development of modern food and beverage industry, fresh-cut vegetables have wider application than before. During the process of sterilization in fresh-cut vegetables, the concentration of chloric disinfectant is usually so high that the common sensor can’t be used directly on the product line. In order to solve this problem, we have invented a new detecting apparatus which could ...

The hypothesis of this research was that under some conditions, monochloramine cometabolism causes disinfectant loss in distribution systems, and is a defense mechanism that allows nitrifiers to persist in pipe-wall biofilm. The research objectives were to (1) define the relative significance of monochloramine cometabolism in causing disinfectant loss over the typical range of conditions encoun...

Qualitative and quantitative tests have been carried out to assess the value of Cidex(1), a glutaraldehyde solution, as a disinfectant. Most of the tests were qualitative and were carried out in conditions as closely resembling those found in hospital practice as possible. Recently used anaesthetic equipment, catheters, and a cystoscope, which had been artificially contaminated with suspensions...

the effect of various pesticides (diflubenzuro, malathion, mancozeb and carbendazim), disinfectants (calcium hypochlorite and formaldehyde) and oil cakes (sunflower and soy-bean oil cakes) commonly used as supplements in mushroom cultivation on the growth of the nematophagous fungus, arthrobotrys oligospora, was studied under in vitro conditions. carbenazim caused 99% inhibition of radial mycel...

Chlorine has been widely used to kill disease-causing microbes in drinking water. During the disinfection process, organic and inorganic material in source waters can combine with chlorine and certain other chemical disinfectants to form disinfection by-products. The kind of disinfectant used can produce different types and levels of disinfectant byproducts in the drinking water, such as trihal...
