The determination wave length is 440 nm,the linear range is 0~50 μg/25 mL,the apparent molar absorptivity is ε=1.3×105,and the limit of detection is 0.035 μg/mL. The recovery of chloride ion in different levels was measured in acidic copper electroplating solution,the result is 95.4%~104.5%.
Acidic Ni-Cu-P bath has been adopted through studying pH value' influence and good corrosion resistance Ni-Cu-P coating has been obtained with smooth and glittering appearance.
Although the materials of nuclear fuel cladding,internal surface and the main reactor internals,and operating temperatures of the pool type light water reactors in China are different from each other. All of pH value of water in the pools are always selected as slight acidity.
This paper discuss the theory and practice about leaching pyrite and pyrolusite directly to get MnSO4 under normal-pressure in the acidity solution, which resolve a problem of poor manganese content of electrolyte in hydrometallurgy of zinc.
From the cyclic voltammetry, the array electrodes in an acidic electrolytic solution had greater capacitance than the case in a neutral electrolytic solution.
On the basis of total acid hydrolysis, methylation analysis, periodate oxidation and NMR studies (1H and 13C) the structure of the repeating unit of the polysaccharide was assigned and indicated only α-(1→4) linked Glucan.
The anticholinergic activity was incorporated into the intact esters to overcome the gastric toxicity of indomethacin, not only by blocking the acidic functionality but also by decreasing gastric secretions and motility.
In a weak acidic medium, the reaction of some aminoglycoside antibiotics (AGs) such as kanamycin sulfate (KANA), gentamycin sulfate (GEN), and tobramycin sulfate (TOB) with acid thiazolyl bisazo dye Titan Yellow (TY) can result in the fading of TY.
On the condition of weak acidity, the sensitive layer was prepared by electropolymerization of o-aminophenol on a gold electrode in the presence of the template (nicotine).
This effect of oxytocin may be mediated through the vagus and sympathetic nerve, and then lead to the reduction of gastric juice output and the depression of gastric acidity.
The NH3-TPD characterization was conducted to confirm that the acidity of Mo-Fe/HZSM-5 zeolite could be selectively modified via the glow discharge plasma treatment.
Moreover, the aggregation stability of the mixed dispersion increased in an acidic region (heteroadagulation stabilization), but decreased in an alkaline region.
It was shown that the spectral characteristics of oxazoleortho-hydroxy derivatives in an acidic medium are formed as a result of competition and interchange of intra- and intermolecular protolytic interactions.
