title: [Comparative study on five pretreatment methods for ICP-OES determination of mineral elements in Rosa rugosa].
abstract: Abstract Five different pretreatment methods, including dry ashing and microwave digestion with four acid systems (HNO3 + H2O2, HNO3 + H2O2 + HF, HNO3 + HClO4 and HNO3 + HClO4 + HF), were employed for digestion of the samples of Rosa rugosa. Nine major and trace elements were determined using ICP-OES method. The addition standard recovery rates indicate that, with the system of HNO3 + HClO4, better results can be obtained for most of the determined elements. With this method, except for Fe, the recovery rates are in the range of 95.4%-104.6%. For Fe, higher recovery rate (99%) was obtained with HNO3 + H2O2 + HF system.
