摘要: A simple, rapid method is given for determination in fish of mercury at concentrations measured parts per million (ppm). Samples are digested 50–60 C with sulphuric acid and oxidised permanganate. Mercury the digest determined by atomic absorption spectrophotometry. Recovery added to samples was complete, good precision. Standard deviations from triplicate analyses were ±0.039 0.1 ppm level ±0.051 0.5 ppm level. In a day, three workers analysed 15–20 triplicate.
