The adsorption of Pb2+ at the rutile/water interface has been studied for the activation of rutile flotation with salicyl hydroxamic acid (SHA) as a collector in this work. This study was performed through measurement of the zeta potential, adsorption capacity, calorimetry and X-ray photoelectron spectroscopy. The experimental results showed that the adsorption of SHA on rutile and the flotability...
The composite nanofibers Ag nanoparticles/carbon nanofibers (Ag NPs/CNFs) were fabricated by electrospinning and high-temperature calcination technology. In the process, AgNO 3 /PAN (polyacrylonitrile)/DMF solutions were used as spinning solution precursor and hydrogen as reducing agent. The as-prepared fibers were characterized by infrared absorption spectroscopy, scanning electron microscopy,...
The superhydrophobic coating was prepared through spraying the mixture of polydimethylsiloxane (PDMS) and hydrophobic nanosilica (SiO 2 ) on the slide glass. The surface of the as-prepared PDMS/SiO 2 coating showed hierarchical roughness with a water contact angle (WCA) of 153°. The resultant superhydrophobic PDMS/SiO 2 coating was subsequently calcined in a muffle furnace...
The organic nano-SiO 2 /acrylate dispersion in which methyl methacrylate (MMA) and butyl acrylate (BA) in the micelles act as dispersing media of nano-SiO 2 was prepared by sol–gel method with tetraethyl orthosilicate (TEOS) as precursor, hydrochloric acid as catalyst and methacryloylpropyl trimethoxysilane (MPS) as modifier. Subsequently, the nano-SiO 2 /fluorinated polyacrylate...
