常用炊具铁、铝和不锈钢锅分别以水、水加醋煮沸10min后，用原子吸收分光光度法测定3种锅加水对应无奈的溶出量（mg／L）分别为铁11．60、铝21．41、镍0.06和铬0．07，而水加醋则其溶出量均明显增加，为加水的2．0－4．5倍。
Common cooking utensils iron, aluminum and stainless steel pot were water, water vinegar boil 10min, atomic absorption spectrophotometric determination of the three pots and water corresponding helpless dissolution (mg / L) were 11.60 iron, aluminum 21. 41, nickel 0.06 and chromium 0.07, while water vinegar its leaching significantly increased, with water 2.0-4.5 times.
