文摘

•: Adsorption takes 4–8 h to reach equilibrium, i.e. fast adsorption kinetics.
•: Surface adsorption occurs at low inhibitor concentrations (<0.04 mM for DTPMP).
•: DTPMP precipitates with calcium on Eagle Ford above 0.04 mM.
•: Iron was extracted from Marcellus under high inhibitor concentrations.
