以蒽为研究对象,研究了不同土壤固、液相组分下蒽的激光诱导荧光发射光谱特性。结果显示,在266 nm激光激发下,土壤蒽在420 nm和444 nm附近分别具有荧光峰,当土壤的原生矿物和次生矿物比例发生变化时,蒽的荧光光谱峰位置未发生明显偏移,420 nm处荧光峰处强度的相对标准偏差为4.52%;土壤中腐殖质种类、浓度改变时,蒽的荧光强度随浓度增大而降低,在不同浓度的腐殖酸和富里酸的土壤中,420 nm处的荧光峰处强度的相对标准偏差分别为38.1% 和27.4%,且正交实验的极差分析结果表明腐殖酸对强度影响大于富里酸;受到重金属污染后的土壤蒽的激光诱导荧光强度明显下降,但液相重金属不同浓度的土壤中,蒽在420 nm处的荧光强度差异不大,荧光峰位置未发生明显偏移.在土壤中含有不同浓度的Cd时,其相对标准偏差为1.60%,含有不同浓度的Cu时,其相对标准偏差为2.05%,含有不同浓度的Pb时,其相对标准偏差为4.54%。因此,采用荧光峰强度定标法测定时,应考虑固液组分变化导致的光谱强度差异。该研究结果为采用激光诱导荧光光谱技术对土壤蒽准确测量提供了基础数据。 |

In this study,anthracene was selected as the research object,and its laser-induced fluorescence emission spectral characteristics in different solid and liquid phases of soil were studied.The results show that the fluorescence peaks for anthracene in soil are at 420 nm and 444 nm induced by a 266 nm laser.When the proportions of primary and secondary minerals in the soil changed,the fluorescence spectral peak positions of anthracene did not shift significantly,and relative standard deviation(RSD)of the fluorescence intensity of anthracene in 420 nm was 4.52%.However,when the species and concentration of humus in the soil changed,the fluorescence intensity of anthracene decreased with increasing concentration The RSDs of fluorescence intensity of anthracene with different concentrations of humic acid and fulvic acid were 38.1% and 27.4% respectively at 420 nm.Moreover,the results of range analysis of orthogonal experiments show that the effect of humic acid was greater than that of fulvic acid In liquidphase heavy metals contaminated soil,the fluorescence intensity of anthracene at 420 nm decreased significantly,and showed little difference in soils with different concentrations of heavy metals in liquid phase,and the positions of the fluorescence peak did not shift significantly.When the concentration of Cd was different,the RSD was 1.60%.When the concentration of Cu was different,the RSD was 2.05%.When the concentration of Pb was different,the RSD was 4.54%.Therefore,when using the fluorescence peak intensity calibration method,the difference in spectral intensity caused by changes in the solidliquid composition should be considered.The obtained results provid the basic research data for accurate measurement of anthracene in soil by using laser induced fluorescence spectroscopy. |
