Dyeing wastewater containing methyl orange (MO) could be effectively discolored by schorl-catalyzed Fenton-like system. Experimental results indicated that the MO discoloration ratios could be increased by increasing schorl dosage, temperature, initial H2O2 concentration, and by decreasing solution pH.

New Mexico Mineral Symposium, 2023
The early history of the mineral schorl shows that this name was in use prior to the year 1400 AD because a village known today as Zschorlau (in Saxony, Germany) was then named ‘‘Schorl’’ (or minor variants of thisname). This village had a nearby tin mine where, in addition to cassiterite, a lot of black tourmaline was found (Ertl, 2006).

Crystal chemistry of the elbaite-schorl series
American Mineralogist, 2005The crystal-chemistry of 13 elbaite-schorl tourmaline crystals from the Cruzeiro pegmatite (Minas Gerais, Brazil) was studied with a multi-analytical approach (SREF, EMPA, SIMS, MS). Effective cation radii at the Y and Z sites and site populations were reÞ ned by a minimization procedure.

Thermodynamics of natural tourmalines—Dravite and schorl
Thermochimica Acta, 2012Abstract The experimental data on the heat capacities and enthalpies of formation from the elements of two natural tourmalines: dravite (Na0.53Ca0.31K0.03)(Mg2.72Al6.22Li0.02Ti0.08Fe0.122+)Si5.92B2.92 (OH)2.85F0.27O27.59 and schorl (Na0.82Ca0.13K0.03)(Fe2.232+Fe0.223+Al5.90Mg0.28Mn0.09Li0.02Ti0.11)Si6.04B3.11(OH)3.00F0.02O27.80 have been obtained ...

Wein‐Wasser‐Mischungen haben eine lange Geschichte, heute sind Schorle und Weinmischgetränke Lifestyle. In der Antike schützte verdünnter Wein dank antibakterieller Wirkung des Alkohols gegen Krankheiten. Heron von Alexandria erfand hierfür einen Automaten, der Wein und Wasser in einem fest vorgegebenen Verhältnis mischt.
