    摘要: The present invention relates to a material notably adapted for the extraction of metal cations in an aqueous medium, comprising a solid support on which are attached polyazacycloalkane compounds having a ring including at least 4 nitrogen atoms, and wherein the nitrogen atoms of the ring are substituted with coordinating groups, which each are independently: a coordinating group of formula: —(CH2)n—C(═O)—NR1R2  or else a both coordinating and binding group, fitting the formula: —(CH2)p—C(═O)—NR3-(A)-[support]. The invention also relates to methods for preparing the aforementioned materials and to different uses thereof, notably for the extraction of Pb2+ cations in an aqueous medium.

    摘要: The strip casting plant has a casting nozzle (10) displaceable in the direction of flow (F) of the liquid metal and adjustable perpendicular to this, to supply liquid metal to the adjustable roller gap (30) between rotating dies (26, 28). The casting nozzle (10) consists of an upper and a lower nozzle element (14, 16) and in vertical strip casting plants a left and a right nozzle element (14, 16) mounted on a melt distribution trough, and two side limiters which form a slot-like outlet opening (20) for the liquid metal. One or both of the nozzle elements (14, 16) is adjustable at least in the area of the outlet opening (20). On operation of the strip casting plant, the casting nozzle (10) is advanced at the start with outlet opening (20) in start position (S) and then withdrawn to work position (W), where the outlet opening (20) is expanded under adaptation to the casting rollers (26, 28).
