を行なう検知管を提供するものである。That is, the present invention creates a new detection tube filled with diphenylcarbazide as the coloring agent 3 and silica gel as the concentration adsorbent 2 inside the transparent capillary tube 1, and places this sensing tube with the coloring agent side facing down. Chromium ions dissolved or dissolved in the solution are caused to rise or be inhaled into the detection tube by capillary action, and react with a coloring agent to form a color, Next, by concentrating and adsorbing this colored band on a part of a concentrating adsorbent, the present invention provides a detection tube that performs qualitative and quantitative analysis of chromium ions quickly and with high sensitivity.
