dc.description.abstract | Spectroscopy which is a fast method had been applied in many field in recent years. Among them, UV/visible spectrophotometer is easy to handle and the price is also comparatively cheap, so it’s become more and more important . But because the UV/visible absorption spectrum is relatively widely, the spectrum will often overlap, especially when the sample is waste water which has complicate composition, it would be difficult to qualitative and quantitative. Therefore, developing a qualitative and quantitative method to analyze samples which have many composition such as waste water , is the important foundation .
This research is mainly to set up basic spectrum database and then develop a qualitative and quantitative method using the database. This method has two parts, the one is to qualitative the composition of samples and estimation the concentration approximately, and the other is to quantitative the concentration of samples accurately.
To measure the absorption spectrum of samples which have one, two, three and four composition respectively, and to calculate the concentration of composition using the method, which had been developed in this research. The results show that it is useful when the composition of samples is only one, two and three, but it is not to work when the composition of samples is complicated. | en_US |
