Uptake kinetics of gas phase nitrous acid (HONO) by a pH-controlled aqueous solution was investigated by using a wetted wall flow tube. The gas phase concentration of HONO after exposure to the aqueous solution was measured selectively by the chemical ionization mass spectrometer in a high sensitive manner. The uptake rate of the gaseous HONO was found to depend on the pH of the solution. For t...

The inhibition behavior of N,N′-bis(2,4,6-trihydroxyacetophenone)-propandiimine (THAPP) as an environmentally friendly Salen Ligand on the corrosion inhibition of mild steel was studied in alkaline solution (pH=10) containing 3% NaCl. Measurements were carried out using electrochemical and surface techniques. The experimental results suggested that this compound was an ...

Alkaline agents are well-known for their disinfection capacities against pathogens even at the presence of organic materials, but the durability of their bactericidal efficacies under field conditions is unknown. Therefore, within the present study, two alkaline agents, namely bioceramic (BCX) derived from chicken feces and food additive grade Ca(OH)2 (FdCa(OH)2) derived from natural lime stone...

In this work, spherical Pt nanometer-scale particles supported on the poly (m-toluidine)/Triton X-100 film modified carbon nanotube paste electrode (Pt/PMT (TX-100)/MCNTPE) was used as a potent catalyst for electrooxidation of formaldehyde (HCHO) in both 0.5 M H2SO4 and 0.1 M NaOH solutions. The obtained results showed that utilization of TX-100 as an additive during the electropolymerization p...

The potential use of the protein denaturant guanidine hydrochloride to inhibit selectively the enzyme activity of serum alkaline phosphatase isoenzymes from liver, bone, intestine, and placenta was investigated. Inhibition of each isoenzyme was shown to be dependent on time and concentration of inhibitor. In the presence of 0-3 mol/l (28.7 g/l) guanidine hydrochloride for 170 seconds 14%, 47%, ...

 Background: The primary coolant is an essential cooling medium used to control heat in a nuclear power plant. During the oxidation process, Nickel may be released in the primary coolant which increases its contamination. The operational problems and high cost of treatment necessitate the research for some newer methods. The aim of this research is investigation of nickel removal from synthetic...

Alkaline phosphatase prepared from mammalian cell cultures was found to have alkaline inorganic pyrophosphatase activity. Both of these activities appear to be associated with a single protein, as demonstrated by: (1) concomitant purification of alkaline phosphatase and alkaline inorganic pyrophosphatase; (2) proportional precipitation of alkaline phosphatase and inorganic pyrophosphatase activ...

PURPOSE To test whether changes in extracellular pH (pHe) in an in vitro preparation of the cat ophthalmociliary artery affect passive tone and agonist responses and whether the endothelial cells are mediators of any pH-induced effect. This will determine the ability of the ophthalmociliary artery to influence retinal and choroidal blood flow in response to metabolic stimuli. METHODS The isom...

Background and purpose: Catechol is a ring form organic compound with high toxicity that is used in petrochemical, pharmaceutical and manufacturing of pesticide. It has adverse effects on human and environmental health if discharged into the environment. The purpose of this study was removal of catechol using catalytic ozonation using core-shell magnetic nanoparticles of iron oxide doped with s...
