DEVELOPMENT OF CELLULOSIC PAPER-BASED TEST STRIPS FOR Cr(VI) DETERMINATION
Paper-based test strips specific for the Cr(VI) determination in aqueous solutions were developed by impregnating a color-forming reagent, diphenylcarbazide, and a quaternary ammonium salt (Aliquat 336) into paper sheets.

Brazilian organoclays as nanostructured sorbents of petroleum-derived hydrocarbons
Organophilic clays were prepared using a bentonite from the town of Boa Vista, state of Paraíba, Brazil, and a quaternary ammonium salt (Genamin CTAC-50). The materials obtained were characterized by X-ray diffraction and infrared spectroscopy.
