Corrosion inhibitor testing in archaeological conservation

Investigation of Furfural as Corrosion Inhibitor in Hydrochloric Acid Solution

Effectiveness of furfural as an organic inhibitor in 5 percent hydrochloric acid which is used in acid pickling of steel was evaluated. Lungmuir, Frumkin and Flory-Huggins isotherms [1, 2] were used to determine the parameters of effective adsorption, free energy and entropy of adsorption. Furfural indicated an inhibition less than 17 percent in concentrations of 0.001 mole per liter for a dura...

Archaeological perspectives on prehistoric conservation in western North America

The archaeological record represents a potentially critical source of information on past relationships between human hunters and populations of game animals. Archaeological research in the last 40–50 years has produced two alternative views on these relationships: one that Native people were knowledgeable, benevolent conservators of game and an alternative that suggests that they depleted and ...
