Pripravki za zaščito lesa na osnovi bakra in etanolamina so nadomestili pripravke na osnovi bakra in kroma. Fiksacija baker-etanolaminskih pripravkov še ni tako učinkovita kot fiksacija ... baker-kromovih pripravkov. Domnevali smo, da etanolamin lahko povzroči depolimerizacijo lignina, ta pa večje izpiranje. Da bi ugotovili razlog za slabo fiksacijo baker-etanolaminskih pripravkov, smo vzorce smreke (Picea abies) in bukve (Fagus sylvatica) impregnirali s 3 različnimi pripravki na osnovi bakra in etanolamina v 3 različnih koncentracijah. Vzorce smo najprej izpirali, zatem pa jim gravimetrično določili spremembo mase. Modul elastičnosti (E) smo merili po nedestruktivni metodi, vzporedno pa analizirali količino bakra, dušika in ogljika v izpirkih. Količino dušika in ogljika smo merili tudi v izpranih in neizpranih vzorcih. Rezultati so pokazali, da prisotnost etanolamina v zaščitnih pripravkih povzroča spremembo modula elastičnosti (E). V izpirkih smo zaznali povečano količino bakra in ogljika ter opazili dobro povezavo med izpranim bakrom in organskim ogljikom. Glavni vir organskega ogljika so bile komponente lesa. S tem smo potrdili zastavljeno hipotezo.
