Title: Comparison of detection for nitrate in vegetables
Abstract: In being used for vegetable,contents nitrate detecting method carry out contrast in common asage,by parallel test and standard recovery.Results: Cadmium post deoxidation follows standard deviation 7.7,relative standard deviation 0.22%.Double wavelength follows standard deviation pair 18.65,relative standard deviation 0.54%.Carbolic acid follows standard deviation 23,relative standard deviation.0.7%.Make use of F-to check that difference,carries out valuation on the data accuracy if existence is notable.The t-being in progress again is checked,is makes valuation out to accurate degree determining result.Conclusion: Cadmium post deoxidation law accuracy accurate degree is maximal.Two wavelength is modeled after taking second place,carbolic acid law is that three kinds method are hit by a minimum's.
