    • Object: This invention provides a method of refining an Rh-containing solution also containing at least one type of impurities of heavy metals, alkaline earth metals, and Ag.Means for solving the problems: The invention provides a method of refining an Rh-containing hydrochloric acid solution also containing Ag and at least one other impurity of heavy metals and alkaline earth metals, the method comprising the steps of: (a) adding an alkali to the solution to adjust pH of the solution to 7-12, whereby generating a neutralized precipitate containing Rh and other components; (b) filtrating and separating the neutralized precipitate; (c) adding a first hydrochloric acid for redissolving the neutralized precipitate in an amount such that the mole ratio of Cl to Rh (mole ratio Cl/Rh) of a resulting solution becomes 3-4; (d) filtering the resulting solution to remove Ag as precipitate, and (e) extracting the solution obtained by the previous step as an aqueous phase with DEHPA.
    • 发明内容本发明提供一种还含有至少一种重金属,碱土金属和Ag的杂质的含Rh溶液的方法。 解决问题的手段本发明提供了一种还含有Ag和至少一种其它杂质的重金属和碱土金属的含Rh盐酸溶液的方法,所述方法包括以下步骤:(a)加入碱 将溶液的pH调节至7-12,由此产生含有Rh和其它组分的中和沉淀物; (b)过滤并分离中和的沉淀物; (c)加入第一盐酸以使中和的沉淀物重新溶解,使得所得溶液的Cl与Rh的摩尔比(Cl / Rh的摩尔比)变为3-4; (d)过滤所得溶液以除去沉淀物,和(e)用DEHPA萃取由前述步骤获得的溶液作为水相。

    • This invention relates to a recording apparatus having a function for reading data on an original, and a function for recording an image corresponding to read data. The recording apparatus of this invention has: an original read unit for reading data on an original; a record unit for recording an image corresponding to the data read by the original read unit on a recording medium; a device for reciprocating the original read unit and the record unit in a main scan direction; and a feed unit for synchronously feeding the original and the recording medium in a sub-scan direction. The original read and record units are moved in the main scan direction, and the original and the recording medium are synchronously fed in the sub-scan direction to record an image corresponding to the data on the original on the recording medium.
    • 本发明涉及具有读取原稿上的数据的功能的记录装置,以及用于记录对应于读取数据的图像的功能。 本发明的记录装置具有:用于读取原稿上的数据的原始读取单元; 用于将与由原始读取单元读取的数据相对应的图像记录在记录介质上的记录单元; 用于使原稿读取单元和记录单元沿主扫描方向往复运动的装置; 以及用于沿副扫描方向同时馈送原稿和记录介质的馈送单元。 原始读取和记录单元沿主扫描方向移动,并且原稿和记录介质沿副扫描方向同步进给,以将与原始数据上的数据对应的图像记录在记录介质上。
