Abstract

An in situ, non-reversible fluorescence sensor (probe) for chloroform has been developed. It is based on a modification of the Fujiwara reaction which produces a red-fluorescent reaction product from chloroform. The reagent is stabilized with a variety of polymeric viscosity modifiers and placed in a small cell. It is covered with a membrane and placed in an aqueous chloroform solution, and the resulting fluorescence is monitored with a small precision filter fluorimeter. The design of an improved optical coupler between the analytical sample and the communication fiber is discussed.
