Worldwide, the presence of pesticide residues in vegetables has been extensively characterized.
A comparative study on acid and hydrothermal methods as ways to reduce interlamellar charge has been carried out on a vermiculite.
A series of vermiculites pillared with mixed precursors of Al–Zr, Al–Hf and Al–Ce were obtained from natural vermiculite subjected to a process of negative harge reduction through hydrothermal treatment.
A natural mineral from Santa Marta-Colombia used as the starting material in the synthesis of pillared clays has been characterized by several techniques, including X-ray diffraction, X-ray fluorescence, electronic...
