Abstract

The present invention provides a method for selective recovery of a valuable metal from a waste denitrification catalyst through alkali fusion, the method comprising the steps of: (a) adding an alkali metal to a waste denitrification catalyst, followed by mixing and alkali fusion, to generate a calcination product; (b) subjecting the calcination product to water-leaching to recover an alkali leachate and a residue; (c) adding a precipitator to the alkali leachate, followed by stirring, to recover calcium metavanadate (Ca(VO3)2) or calcium tungstate (CaWO4) through precipitation; and (d) subjecting the recovered calcium tungstate to acid decomposition to prepare tungstic acid. Therefore, vanadium and tungsten can be recovered at high efficiency by a method in which a precipitator is added to a leachate, which is obtained by adding an excess amount of an alkali metal to a waste denitrification catalyst and carrying out calcination and water-leaching, and then a reaction rate is controlled.

Abstract

The present invention relates to an air-coupled type bistatic ground penetrating radar (GPR) antenna and, more specifically, to an air-coupled type ground penetrating radar (GPR) antenna which reduces reception of a direct wave, which is a factor limiting imaging performance of a system when being received at a receiving side of the GPR antenna, by placing a loop antenna at a receiver point so as to be vertical to an antenna plane with respect to a polarization direction of a transmitting antenna and configuring a feeding direction to be orthogonal to a feeding direction of a transmitter and the ground surface. The air-coupled type GPR antenna, which is spaced apart from the ground, comprises: the transmitting antenna directed towards the ground and penetrating a radio wave into the ground; and a receiving antenna receiving a radio wave, which is radiated from the transmitting antenna and then reflected from the ground, and fed in a direction perpendicular to the ground surface and the feeding direction of the transmitting antenna. The transmitting antenna uses an antenna, such as a horn antenna, having directivity and the receiving antenna uses a loop antenna in which a physical plane of the antenna is positioned to be perpendicular to the ground surface with respect to the polarization direction, thereby resulting in the effect of improving radar detection performance of an air-coupled type GPR system.
