摘要

HOE 80/B 008 of the disclosure: Test agent for the detection of coupling compounds , and a process for its preparation A test agent for the detection of coupling compounds in liquids is described, which essentially consists of an adsorbent matrix containing a diazonium salt as the reagent and a stabilizer for this diazonium salt, this stabilizer being a phosphonium salt. Furthermore there is described a process for the preparation of said test agent.
