Ammonia is the primary attractant for tephritid fruit flies, and traps baited with synthetic attractants using ammonia formulations have been highly successful in capturing these pests. However, difficulties in quantifying release rates of ammonia have limited abilities to make comparisons among field tests of different species by using different formulations. Therefore, Fourier transform infra...

An aquaculture system can be a potentially significant source of antibacterial compounds and ammonia in an aquatic environment. In this study, the removal of total ammonia nitrogen and florfenicol antibiotic from synthetic aqueous wastewater was assessed by applying a commercial TFC (thin film composite) polyamide nanofilter. The effects of pH (6.5-8.5), pressure (4-10 bar), concentration of to...

The course and magnitude of spontaneous increase in ammonia concentration in plasma on standing were investigated with EDTA-treated blood specimens from 36 healthy subjects with use of a sensitive and precise enzymic method. Over 90 min, the rates of increase were virtually constant at fixed temperature. The mean (and SE) rates at 0, 20, and 37 degrees C were 3.9 (0.23), 5.2 (0.23), and 25.2 (0...

Nitrogen constitutes 78.09% by volume of dry unpolluted air, but it is a minor element with respect to its abundance in the earthj:"crust. Atmospheric nitrogen forms an important raw material for the economical synthesis of bulk chemicals of industrial importance, viz. ammonia, urea, nitrate, nitrite etc. Therefore, estimation of ammonia and its derivatives assumes a great importance for chemic...

This work describes the preparation of new carboxymethyl guar gum-silver nanocomposite (CMGG/Ag NC) by green synthesis method. For this carboxymethyl guar gum was used as a reducing agent as well as stabilizer. The silver nanoparticles obtained were characterized by field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), UV–vis spectroscopy, Fourier transfo...
