The organosoluble gold salts are easily separated from sulfate byproducts by direct extraction into the benign solvent ethyl acetate, which is also easily recycled for re-use, providing a strategy for gold activation and dissolution without any additional reagents for purification, such as cation exchange resins, salts, or chelating agents. The methodology is based on solventless, mechanochemical oxidation of metallic gold with Oxone® in the presence of tetraalkylammonium halide salts, to directly, rapidly (within 30–60 minutes) and at room temperature convert gold metal into solid salts that are immediately soluble in pure organic solvents and aqueous alcoholic media. Here, we describe a methodology that simultaneously avoids aggressive reagents and enables gold extraction into a safe organic solvent. As a result, development of safer, cleaner processes that would enable gold processing in non-aqueous, organic solvent is an attractive technological goal. Substructure system to realize a wall mounting composed on single and double beams in galvanized steel sheet with Bollhoff system for quick fixing of panels and side finishing covers, metal covers’ finisching are available in matt white and matt brown colors.Gold is highly valued for a wide range of commercial and technological applications but is processed exclusively through highly aggressive and toxic solvents and/or reagents, ultimately yielding water-soluble salts that are difficult to separate from inorganic reaction byproducts. It has certificate sound absorption rate, according to the UNI EN 354:2003 e UNI EN ISO 11654:1998. MOSSwall® is certificated for fire by a main italian certification institute classification of reqction to fire according to the UNI EN 13501 - 1 : 2009 and ASTM E 84 :2015.

The panel is designed for wall mounting through 4 holes and is equipped with an interlocking system to put the panels together. MW02 same composition of MW01 but panel designed for cutting lines and wall finisching. Panel 40圆0 cm in galvanized steel covered permanentely with PVC film. MOSSwall® is the innovative system for indoor vertical gardens that need no maintenance, it is patented by Verde Profilo®. MOSSwall® by Verde Profilo®: Tecnichal layout
