The pH, moisture, organic matter content, loss on ignition and swelling power of matured and non-matured samples were measured for physicochemical characterization. The elemental concentration was determined by instrumental neutron activation analysis. Results showed that pH, moisture (%) and LOI (%) at 1000 ºC did not change after maturation for all samples and an increase in the organic matter (%) was noted for all samples, mainly in the peloids treated with Peruíbe sea water. The concentration of As, Ba, Br, Ca, Ce, Co, Cr, Cs, K, La, Na, Yb and Zn has changed after the maturation process in both clays and the Br and Na concentration has changed in both clays when matured with sea water from Peruíbe. 2019 artículo científico 2319-0612 https://www.redalyc.org/articulo.oa?id=722280838091 en http://www.redalyc.org/revista.oa?id=7222 Brazilian Journal of Radiation Sciences application/pdf Sociedade Brasileira de Proteção Radiológica - SBPR Brazilian Journal of Radiation Sciences (Brasil) Num.2A Vol.7 |
