氯离子与硫氰酸汞反应,生成难解离的氯化汞,同时释放等量的硫氰酸根离子;后者与试剂中的铁离子结合,形成橙红色的硫氰酸铁。该产物在480 nm波长处有最大吸收,其显色强度与氯离子浓度成正比。
Chloride ions react with mercuric thiocyanate to form weakly dissociated mercuric chloride, simultaneously releasing an equivalent amount of thiocyanate ions. The released thiocyanate ions then combine with ferric ions (Fe³⁺) present in the reagent to form orange‑red ferric thiocyanate. This product exhibits maximum absorption at a wavelength of 480 nm, and its color intensity is directly proportional to the chloride ion concentration.
