[求助] 麻煩幫忙潤色一段話，謝謝！

However, the compositions of sewage and sludge samples are more complex than those of samples above because of high content of organic matter. Hence, there is a need for suitable sample pretreatment schemes, which is in good agreement with those for determination of total As by HG-AFS methods. On the other hand, the procedure aiming at the optimization of complete sample digestion leading to reliable and rapid methods without loss of analyte should be considered. Till now there were no relevant reports on the determinations of total As in sewage and sludge samples by using the same method of complete digestion.
大致意思是：然而，污水、污泥樣品中由于含有高濃度有機(jī)質(zhì)，比前述樣品成分更加復(fù)雜，因此，需要采用一個(gè)合適的樣品前處理方法以確保可以采用HG-AFS方法測定其中總砷。此外，還需考慮優(yōu)化的、完善的樣品預(yù)處理方法的快速、可靠和低損失。截至目前，還未見采用同一消解方法對污水、污泥中TAs進(jìn)行測定。

However, the compositions of sewage and sludge samples are more complicated than those of the former samples due to the high concentration organic matters.Thus,an appropriate pretreatment scheme is needed to ensure that HG-AFS method can be applied to determine the total arsenic. In addition, the speediness, reliablity and low loss of the optimized and perfect sample pretreatment method should be considered. Up to now, there have been no relevant reports on the determinations of total As in sewage and sludge samples by using the same method of complete digestion.
