目前测定银的高灵敏度方法不多,尤其是水相比色测定更为少见。现将较灵敏的光度比色测定银的各种方法比较如下。由表1可知,目前测定银大多使用有毒性的有机
At present, there are not many methods to determine the sensitivity of silver, especially the colorimetric determination of water is more rare. Now more sensitive photometric colorimetric silver method is as follows. As can be seen from Table 1, the current determination of silver is mostly toxic and organic
