Based on limestone wet desulfurization spray scrubber technology, this paper explicitly introduces the ionization process of water in slurry, deduces controlled range of slurry PH value and equation of slurry PH value in slurry droplet by analyzing the main origin of H+ and OH-, and other factors that influence ionization balance of water in slurry, provides theories for simulation of slurry PH value...
The bio-hydrogen producing process has complex interactions; thus, constructing a detailed mechanistic model and proper control architecture is difficult. Artificial neural networks (ANNs) are capable of inferring the complex relationships between input and output process variables without a detailed characterization of the mechanisms governing the process. This work presented a novel ANN that accurately...
Humic acid (HA) was considered to be the main precursor of disinfection by-products (DBPs) in chlorination. In this study, an effective and economic method of preparing TiO2 film was successfully developed for adsorption of HA. The crystal structure and surface morphology of the TiO2 film were characterized by X-ray diffraction (XRD) and atomic force microscopy (AFM). The effects of some factors such...
A new catalytic kinetic spectrophotometric method for the determination of trace amount of manganese (II) (Mn (II)) in microemulsion medium has been developed. The method is based on the catalytic effect of Mn (II) on the oxidation of nuclear fast red by potassium periodate with Nitrilotriacetic Acid (NTA) as an activitor in the presence of Tween-80/n-butanol/n-heptane microemulsion and HAc-NaAc buffer...
Numerical modelling and simulation of Koutecky-Levich equation for NADH electrocatalytic oxidation at graphite electrodes modified with a polymer of phenothiazin formaldehyde (PPF) was performed. There were obtained the second order electrocatalytic rate constants (kobs,[NADH]=0) from rotating disk electrode experiments, at various concentrations of NADH and phosphate buffer with different pH values.
