PURPOSE: To efficiently reutilize resources, to form an effective recycling line and to recover hydrochloric acid and copper sulfate by separating and recovering the useful hydrochloric acid and copper sulfate from a waste copper chloride soln. discharged from an etching stage.山田 慶太...
One of the most important applications of hydrochloric acid is in the “pickling of steel” to remove rust or iron oxide scale from iron or steel before subsequent processing, such as extrusion, rolling, galvanizing, and other techniques. Technical quality HCl at typically 18% concentration is th...

Copper Be Gone: The Chemistry Behind PCB Etching August 31, 2023byDan Maloney37 Comments For a lot of reasons, home etching of PCBs is somewhat of a dying art. The main reason is the rise of quick-turn PCB fabrication services, of course; when you can send your Gerbers off and receive...
It appears light yellow when it contains traces of iron (iron oxide), free chlorin e or organic matter. Strong acid, can be mixed with water and ethanol in any ratio. Strongly corrosive, can be neutralized with alkali, and has no effect with phosphorus, sulfur and other non...
. It is also used to pickle metals, i.e. clean the surface prior to electroplating. Hydrochloric acid donates protons with ease and is the strongest of the hydrohalic acids. The concentrated acid is oxidized to chlorine by such agents as potassium manganate(VII) and manganese( IV) oxide....

2.2. Preparation of copper oxide nanoparticles (CuO–NPs) (CuO–NPs) were synthesized by nitrate-precursor auto-combustion method (sol–gel method). Stoichiometric amounts of copper nitrate were dissolved in a small amount of distilled water, then citric acid monohydrate was added dropwise to coppe...
