Zusammenfassung:The invention discloses a measuring method and a processing method of metal in gelatin. The measuring method comprises a step of sample preparation, and a step of measuring samples to be measured using atomic absorption method. The sample to be measured is prepared through following steps:1, pre-digestion, wherein a gelatin sample is immersed in nitric acid so as to obtain a pre-digested solution;2, microwave digestion, wherein the pre-digested solution is introduced into a microwave generation equipment for 5 to 10min of a first time of microwave treatment at 120 to 130 DEG C, 5 to 10min ofa second time of microwave treatment at 150 to 160 DEG C, and 10 to 20min of a third time of microwave treatment at 180 to 190 DEG C, and then is cooled to room temperature so as to obtain a microwavedigested solution; and 3, evaporation acid removing, wherein the microwave digested solution is subjected to a first time of evaporation acid removing for 10 to 20min at 120 to 150 DG C, a second time of evaporation acid remov
