主题：【求助】乙磷铝检测方法

高难度啊，查不到方法，不过查出来是有机膦类杀菌剂……不知道液相能做不能

最近要检测乙磷铝,查到一个日本的方法，好象很麻烦，哪位有好的检测方法,请指点一下,谢谢!

乙磷铝肯定要用单独法,应该不会太简单的,有几种农药大家公认难检.

它的性质决定了它就是难检,很简单的方法可能性不大.毕竟又要提取还要净化的.

Determination of fosetyl-aluminium in the presence of folpet

A modified spectrophotometric method for determination of fosetyl-aluminium in the presence of folper was developed. The method is based on melting samples in heating furnace at a temperature of 800-900 deg C. The residues obtained were oxidized, and phosphonate from fosetyl-aluminium was converted into phosphate by adding solutions of nitric acid and hydrogen peroxide. Phosphate was determined spectrophotometrically at 440 nm with the molibdate-vanadate reagent. Based on phosphate content (as P2O5), fosetyl-aliminium content can be determined, taking into account that three moles of P2O5 are obtained from two moles of fosetyl-aluminium. Based on the values of relative standard deviation and recovery, it may be concluded that the proposed method is relatively reproducible and accurate.

Potential of liquid chromatography-atmospheric pressure chemical ionisation tandem mass spectrometry for determination of fosetyl-aluminium residues in dried hops.

Abstract:
New analytical procedure for the determination of fosetyl-aluminium in hop cones (also called "hops") was developed. Liquid chromatography-atmospheric pressure chemical ionization tandem mass spectrometry (LC-APCI-MS/MS) allowed a highly selective determination of this fungicide which facilitated the sample preparation. The sufficiently low detection limit (1 mg/kg of dried hops) with the acceptable method performance characteristics (RSD 9%, recovery 76% - at the level of 10 mg/kg) complies with the need to inspect the observance of maximal residual limit of 100 mg/kg. The application of LC-MS technique thus provided an effective way of fosetyl-aluminium determination in the complex hops matrix.

消解后测磷和铝的量，就可以推论结构！！不过是高含量的方法，容量法滴定或者是分光光度法！！

楼上,有没有翻译过来的检测方法,英文的看起来比较吃力.翻译过来的别的方法也行啊.谢谢!

你好！暂时没有找到中文的相关资料，其实英文的方法不是很难理解的，都是程序式的描述。
