摘要： Disclosed is a method for effectively leaching valuable metals such as vanadium and tungsten contained in a waste denitrification catalyst by using roasting and water leaching. According to the present invention, the method for leaching valuable metals contained in a waste denitrification catalyst comprises the steps of: (a) mixing a waste denitrification catalyst containing vanadium (V) and tungsten (W) in the form of an oxide with an alkali metal compound to form a mixture; (b) roasting the mixture to generate a roasting product comprising sodium vanadate (NaVO 3 ) and sodium tungstate (Na 2 WO 4 ); and (c) injecting the roasting product into water to water leach sodium vanadate and sodium tungstate in the form of a vanadate ion (VO 3 - ) and a tungstate ion (WO 4 2- ).

摘要： Disclosed herein is a monitoring probe for observing groundwater, which is put into an observation well for observing the groundwater to indicate a position of a fresh water-salt water interface of the groundwater. According to the present invention, both ends of a probe body are separated from an inner circumference of an observation well by a catch preventing portion having a convex curved portion or a dumbbell-shaped portion, so that the probe body can be smoothly moved up and down without being caught by a ground-water inlet port of the observation well, thus providing an exact position of a fresh water-salt water interface.

摘要： The present disclosure provides a method for adsorption/desorption of lithium ions from brine, which employs a counter current decantation process in adsorption/desorption of lithium ions, thereby achieving an adsorption rate of 65 ± 5% and a desorption rate of 95 ± 3%. The method includes supplying brine into one of a plurality of adsorption reactors, adsorbing lithium ions to an adsorbent by supplying the adsorbent to the adsorption reactor to which the brine is supplied and forcing the brine and the adsorbent to sequentially flow backwards inside the respective adsorption reactors, and desorbing the lithium ions from the brine by forcing the adsorbent to which the lithium ions are adsorbed to sequentially flow backwards inside a plurality of desorption reactors. Here, the brine and the adsorbent are stirred by a stirrer to maintain the adsorbent in an intermediate state instead of settling or floating inside the respective adsorption reactors, after supplying the adsorbent to the adsorption reactor to which the brine is supplied.
