Kysel\u00fd d\u016fln\u00ed odtok (KDO) je hlavn\u00edm environment\u00e1ln\u00edm probl\u00e9mem v oblastech s opu\u0161t\u011bn\u00fdmi uheln\u00fdmi doly. Kdy\u017e voda prosakuje do t\u011bchto dol\u016f, reaguje s miner\u00e1ly v hornin\u011b a vytv\u00e1\u0159\u00ed kyselou vodu, kter\u00e1 je zat\u00ed\u017eena \u017eelezem a dal\u0161\u00edmi kovy. Tento toxick\u00fd odtok te\u010de do potok\u016f, sni\u017euje jejich pH, zab\u00edj\u00ed ryby a ni\u010d\u00ed stanovi\u0161t\u011b.<\/p>\n\n
Profesor environment\u00e1ln\u00edho in\u017een\u00fdrstv\u00ed Guy Riefler a profesor um\u011bn\u00ed John Sabraw vid\u011bli v tomto toxick\u00e9m odtoku p\u0159\u00edle\u017eitost. Uv\u011bdomili si, \u017ee oxidy \u017eeleza ve vod\u011b by mohly b\u00fdt pou\u017eity k vytvo\u0159en\u00ed pigment\u016f pro barvy.<\/p>\n\n
Riefler a jeho studenti vyvinuli metodu, jak extrahovat \u017eelezit\u00fd kal z potok\u016f zasa\u017een\u00fdch KDO. Pot\u00e9 oxiduj\u00ed \u017eelezo v kalu, co\u017e zp\u016fsob\u00ed, \u017ee vyvine z\u00e1\u0159iv\u00e9 barvy. \u017delezit\u00fd kal se pot\u00e9 su\u0161\u00ed a mele na jemn\u00fd pr\u00e1\u0161ek, kter\u00fd lze p\u0159idat do olejov\u00fdch nebo akrylov\u00fdch pojiv, aby vznikla barva.<\/p>\n\n
Barvy vyroben\u00e9 z pigment\u016f KDO maj\u00ed \u0161irokou \u0161k\u00e1lu barev, od ho\u0159\u010di\u010dn\u011b \u017elut\u00e9 po tmav\u011b hn\u011bdou. Sabraw, kter\u00fd tyto barvy za\u010dlenil do sv\u00e9ho um\u011bleck\u00e9ho d\u00edla, \u0159\u00edk\u00e1, \u017ee maj\u00ed odli\u0161nou konzistenci a kvalitu, kter\u00e1 je srovnateln\u00e1 s jin\u00fdmi komer\u010dn\u00edmi barvami.<\/p>\n\n
Rieflerov\u00fdm c\u00edlem je vytvo\u0159it ekonomicky \u017eivotaschopn\u00fd n\u00e1t\u011brov\u00fd produkt, kter\u00fd m\u016f\u017ee pomoci vy\u010distit zne\u010di\u0161t\u011bn\u00e9 potoky v Ohiu. Pigmenty lze vyr\u00e1b\u011bt ve velk\u00e9m mno\u017estv\u00ed z vysoce produktivn\u00edch pr\u016fsak\u016f KDO, co\u017e p\u0159in\u00e1\u0161\u00ed zna\u010dn\u00e9 p\u0159\u00edjmy. V\u00fdt\u011b\u017eek z prodeje barev by byl pou\u017eit k financov\u00e1n\u00ed projekt\u016f obnovy tok\u016f, vytv\u00e1\u0159en\u00ed m\u00edstn\u00edch pracovn\u00edch m\u00edst a zlep\u0161en\u00ed kvality vody.<\/p>\n\n
Sabraw pou\u017e\u00edv\u00e1 sv\u00e9 obrazy vytvo\u0159en\u00e9 s pigmenty KDO, aby zv\u00fd\u0161il pov\u011bdom\u00ed o \u0161kod\u00e1ch na \u017eivotn\u00edm prost\u0159ed\u00ed zp\u016fsoben\u00fdch t\u011b\u017ebou uhl\u00ed. Jeho pr\u00e1ce zd\u016fraz\u0148uje kr\u00e1su, kterou lze nal\u00e9zt na ne\u010dekan\u00fdch m\u00edstech, a to i uprost\u0159ed zne\u010di\u0161t\u011bn\u00ed.<\/p>\n\n
Projekt transformace toxick\u00e9ho odpadu na barvu je pr\u016fkopnick\u00fdm modelem pro n\u00e1pravu tok\u016f. Ukazuje, jak lze odpadn\u00ed produkty p\u0159em\u011bnit na cenn\u00e9 zdroje a z\u00e1rove\u0148 \u0159e\u0161it environment\u00e1ln\u00ed probl\u00e9my.<\/p>\n\n
Riefler d\u00e1le zdokonaluje proces v\u00fdroby barev a experimentuje s r\u016fzn\u00fdmi prom\u011bnn\u00fdmi, aby optimalizoval kvalitu a konzistenci pigment\u016f. Tak\u00e9 zkoum\u00e1 partnerstv\u00ed s prodejci pigment\u016f, aby uvedl barvu na komer\u010dn\u00ed trh.<\/p>\n\n
