Alternatively, the copper oxide may also directly react with CO2, H2O, and sulfur oxides to form the compounds brochantite, malachite, and azurite: ☞ Brochantite is mainly formed when high level of sulfur fumes are present. Although the immunosensor initially showed little current signal due to the poor conductivity pf ZIF-8 and PVA, the current signal was significantly amplified by a HCl-triggered cascade reaction. Most metals are gray or silver. The dissolved copper creates cupric chloride which can itself be used to etch metal. Copper is one of the few coloured metals. Generally, H2O2 is frequently adopted to improve analysis capabilities of various detection systems. The H2O2 process works with a success rate of about 1 in 8 attempts (for me). It can be produced industrially by heating copper metal to a high temperature, by the electrolysis of salt solutions using copper electrodes, and by mixing some other copper compounds with a reducing agent. Since hair is protein-based, hydrogen peroxide attacks melanin and the structure of hair in equal measures.
