Stripping voltammetry and conductance measurements were used for the first time to study the corrosion and inhibition of copper. The effect of nitric acid concentration, temperature and some organic compounds on the corrosion rate was studied. Regression analysis using four modes (linear, logarithmic, ...

The anodic dissolution of copper in chloride solutions was studied under laboratory conditions up to 101 C and up to 175 C in a specially designed cell that could be flanged into a pump loop. Under all conditions the anodic polarization curves demonstrated Tagel behavior with slopes equal to 2...
Simultaneous determination of trace lead、copper and mercury by anodic stripping voltammetry; 碳糊电极阳极溶出法同时测定水中微量铅、铜、汞 2. By means of electric potential method and anodic stripping voltammetry, the trace Cd~(2+) in the soil samples of rich iron content can be determined by...

ASI Ahmed,KJ Friesen,AS Abd-Al-Aziz - 《International Journal of Science & Technoledge》 被引量: 0发表: 2000年 The anodic behaviour of copper in static and flowing hydrochloric acid solutions The dissolution of copper in 0·36 to 3·6 HCl was studied both in static and in flowing solution...
Copper may be separated from its mixture with an iron-nickel-cobalt alloy by selectively removing the copper by use of a nitric acid concentration in excess of 10À5 N, preferably 12 N or greater, whilst the alloy can be removed by the use of a nitric acid concentration of 1À5 N. ...
The transition metal catalyst may contain any transition metal, for example, copper (Cu), iron (Fe), ruthenium (Ru), nickel (Ni), osmium (Os), or combinations thereof, and the initiator may be an alkyl halide. In an ATRP process, a dormant species is activated by the transition metal ...
Taking the mixing liquor of nitric acid, ammonium chloride and potassium permanganate as mixing solvent to decompose ore sample in zealed and pollution-free container,metals as silver, copper,lead and zine can be determined synchronously by atomic absorption method. 本文以硝酸+氯化铵+高锰酸钾+氢氟...
