Aquatic mercury ion detecting system based on nanometer gold colloid

The utility model relates to a does aquatic mercury ion detecting system based on nanometer gold colloid compare groove, sample detecting groove, nanometer gold reagent interpolation groove, 4' 4 by distilled water bipyridine reagent adds the groove, and pipe and colorimetric card are constituteed, put into sample detecting groove and distilled water contrast groove respectively with sample detecting and distilled water, then add the groove by nanometer gold reagent and pass through the pipe to sample detecting groove and the good nanometer gold colloid of distilled water contrast groove joining configuration, ' 4 again by 4 does bipyridine reagent add 4' 4 of groove to sample detecting groove and distilled water contrast groove joining equivalent isoconcentration bipyridine solution. After waiting for that solution takes place colour variable, compareing the groove with the sample detecting groove contrasts with distilled water, can confirming among the sample detecting whether exceed the standard of mercury
