Refining waste hardmetals into tungsten oxide nanosheets via facile method
Source abstract
Abstract
A new hydrothermal system has been designed to recycle waste WC–Co hardmetal with low cobalt (Co) content (3 %). In the solution system, nitric acid was designed to dissolve Co, H2O2 served as oxidant to accelerate the oxidation of the WC–Co hardmetals, and fluorine (F−) was designed to dissolve and recrystallize generated tungsten oxides, which were found to possess a layered structure using scanning electron microscopy and transmission electron microscopy. The obtained tungsten oxides were identified as WO3·0.33H2O by X-ray diffraction and their specific surface area was measured as 89.2 m2 g−1 via N2 adsorption–desorption techniques. The present layered structure tungsten oxides exhibited a promising capability for removing lead ion (Pb2+) and organic species, such as methyl blue. The adsorption model was found to be in agreement with Langmuir isotherm model. Given the facile synthesis procedure and promising properties of final products, this new approach should have great potential for refining some other waste hardmetals or tungsten products. A new hydrothermal system was designed to recycle waste hardmetal with low cobalt content. Through this method, waste hardmetal was refined into WO3·0.33H2O nanosheets which shows excellent adsorption capacities toward methylene blue and lead ion (Pb2+).
