摘要： Disclosed are a controlled-release composition for oral administration comprising a complex of a hydrophilic alpha adrenergic blocker compound or its salt; and a clay mineral, and a method for preparing the same. The composition of the present disclosure has an in vivo release rate controlled further than that of conventional alpha adrenergic blocker compounds, thereby preventing side effects caused by a rapid increase in plasma drug concentration.

摘要： 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.

摘要： The present disclosure relates to an onshore lithium-recovering device for a lithium ion adsorption and desorption process including a supply unit for supplying lithium-containing water in which lithium is dissolved, a composite unit, a washing unit, a desorbing liquid unit, an extract liquid unit, a pressure adjusting unit, a discharge unit, and a control unit. Therefore, the lithium adsorption means is moved onshore so it is possible to significantly reduce the plant installation cost and the operating cost as compared to the lithium recovery process that operates the conventional offshore plant.
