[New development of modern photometric determination of trace aluminium in environmental samples].

In this paper, new development of modern photometric determination of aluminium in environmental samples in recent years was reviewed and discussed. The new development in modem photometric determination of aluminium in environmental samples was emphasized, including micelle photometric method, dual-wavelength photometric method, derivative photometric method, catalytic photometric method, solid phase photometric method and flow injection photometric method. Reaction systems of determination and it's conditions, molar absorption coefficient (epsilon) or the limit of detection, the scope of determination and applications of the ordinary photometric method, and the micelle photometric method were summarized. Advantages and disadvantages of all kinds of photometric methods were discussed. The development trend of photometric method was prospected for the detection of trace aluminium in environmental samples.
