测定某含铜样品中的微量锰时,在酸性溶液中用KIO[img=~/QImg/2013-10-14-10-14-34/image002.jpg](无色)氧化Mn[img=~/QImg/2013-10-14-10-14-34/image007.jpg]到MnO[img=~/QImg/2013-10-14-10-14-34/image021.gif]进行分光光度法测定(铜盐溶液为蓝色),应选择的空白溶液是
A、去离子水
B、KIO[img=~/QImg/2013-10-14-10-14-34/image002.jpg]溶液
C、加KIO[img=~/QImg/2013-10-14-10-14-34/image002.jpg]的试样溶液
D、不加KIO[img=~/QImg/2013-10-14-10-14-34/image002.jpg]的试样溶液
