[求助] 请大家帮忙分析这个审稿意见怎么回答呢?做过水样基质影响的一定进来帮忙啊!

1) Reviewer 1 placed some interesting questions regarding the filtration/spiking of the samples and the matrix effect. If I agree with the authors regarding to the filtration, that is a standard procedure. Independently of the PAHs adsortion to particulate matter, normally what is measured is the soluble phase. Another type of methodology should be employed considering particulate matter or other phase, what is not the focus of the present manuscript. However, Reviewer 1 has a point regarding matrix effect. It is very typical in new methodologies to show that there is no significant difference between an external calibration or a standard addition method. In other cases, and very usual for PAHs analysis, internal standards may also be employed to overcome this matrix effects. But this is not theory that is checked against the literature but actually measured. When the authors present a method for water analysis, it includes all type of water samples even wastewater, correct? Wastewater can be a very complex matrix.

审稿人1觉得水样分析之前不要过滤,因为过滤会滤去颗粒物,而水中污染物的分析不仅包含溶于水的,还应包含颗粒物吸附的。但是文献基本都过滤了,这应该是一个常规程序吧?所以审稿人2是这么认为的。但是他们都认为要考虑基质的影响,可是我见过的水样分析的基本不做基质影响啊!我修改的时候,是纯水和实际水样各自处理了进样,比较峰面积,大小在20%以内表示基质不受影响。有没有具体做过水样基质影响的啊?我不确定我做的对不对。请大侠们帮忙!十分感谢!!
