Spectroscopic study of copper adsorption by chitosan and lignin composites containing layered double hydroxides

Autor: Cesar Gomez Hermosillo, Rodolfo Ortiz Castillo, Marta Eliane Doumer, Gregorio Guadalupe Carbajal Arízaga, Antonio Diaz Hernández

Publikováno v: Journal of Electron Spectroscopy and Related Phenomena. 226:1-8

Lignin and chitosan are two widely available biomaterials which provide the base for designing biosorbents that remove heavy metals from water. On the other hand, layered double hydroxides (LDH) are well-known synthetic clays with the ability to remo

Spectroscopic Study of Sediments from Chapala Lake in Western Mexico

Autor: Marta Eliane Doumer, G. Álvarez Lucio, A. García Huerta, Antonio S. Mangrich, S. Gómez Salazar, G. G. Carbajal Arízaga

Publikováno v: Journal of Applied Spectroscopy. 83:888-895

The first 10 cm of sediment from Lake Chapala, Western Mexico are in constant activity related to the exchange and speciation of metal cations. Samples of this sediment were analyzed in electron paramagnetic resonance (EPR) equipment to study the par
