Abstract

We studied two groups of samples called La Calera� and Amotape � in situ from the Peruvian districts of Alto Laran and Amotape respectively. Different techniques were needed to characterise them. By using X-ray diffractometry we determined their phases as well as corroborated the cation exchange process in some samples; however in other samples there was a large interplanar spacing. Through transmission Mssbauer spectroscopy we obtained the valence state of iron. Consequently we determined that the samples contained calcium and sodium clays. Additionally we proceeded to optimise the calcium clays by cation exchange to obtain sodium clays which can be used in wastewater treatment and other applications.
