Raman spectroscopy of basic copper(II) and some complex copper(II) sulfate minerals: Implications for hydrogen bonding
Studies of the basic Cu sulfate minerals have existed for some time (Fowles 1926; Richmond and Wolfe 1940; Ungemach 1924). Such minerals are formed under specific conditions of pH and sulfate ion concentration. The minerals in this group are dolerophanite Cu2OSO4 (Richmond and Wolfe 1940), antlerite Cu3SO4(OH)4 (Araki 1961; Finney and Araki 1963), brochantite Cu4SO4(OH)6 (Helliwell and Smith 19...
متن کاملCorrosion Behavior of Copper in Chloride Media
The electrochemical behavior of copper in 0.05 M HCl and 0.05 M NaCl carried out at open-circuit potential and at constant anodic potential after one hour has been investigated using electrochemical impedance spectroscopy (EIS) at 20 °C, 40 °C and 60 °C. The formation of copper chloride (CuCl) film does not protect copper from dissolution in the chloride media. The physical properties of the pa...
متن کاملNew inhibitors for copper corrosion *
The study of the effectiveness of several potential copper corrosion inhibitors in acidic media was studied. The investigated thiazole derivative functional groups contain heterocyclic atoms such as nitrogen, sulfur, and oxygen. Thiazole derivatives, 5-benzylidene-2,4-dioxotetrahydro-1,3-thiazole (BDT) 5-(4′-isopropylbenzylidene)-2,4-dioxotetrahydro-1,3-thiazole (IPBDT), 5-(3′-thenylidene)-2,4-...
متن کاملTribasic copper chloride and copper sulfate as copper sources for weanling pigs.
We conducted three 28-d experiments involving a total of 915 pigs to assess the relative efficacy of tribasic Cu chloride (Cu2[OH]3Cl) and Cu sulfate pentahydrate (CuSO4.5H20) in diets for weanling pigs. Experiments 1 and 2 were conducted at an experiment station (University of Kentucky), and Exp. 3 was conducted at a commercial feed company's swine research facilities (United Feeds, Inc.). The...
