In the present work, surface interaction of L-alanine (L-ala) has been investigated on hematite (α-Fe2O3), an abundant mineral on Mars, as a function of time (5 min–48 h), pH (4.0 and 6.20 ± 0.10) and concentration (1 × 10−3 M–10 × 10−3 M) with optical absorbance and energy-dispersive spectroscopy (EDS). Adsorption parameters (XM and KL) were calculated… CONTINUE READING
