【摘要】：應(yīng)用電噴霧電離源結(jié)合傅立葉變換離子回旋共振質(zhì)譜(ESI FT-ICR MS)對(duì)地下水進(jìn)行分析,基于高精確度的分子量檢測(cè)結(jié)果,鑒定出O_x,N_1O_x和N_2O_x3大類,共計(jì)27小類含雜原子的化合物。雜原子化合物中O_x類化合物占絕大多數(shù),而含N化合物則以結(jié)合大量氧原子的形式廣泛存在。結(jié)合各類雜原子化合物的等效雙鍵數(shù)(DBE)及碳數(shù)分布,發(fā)現(xiàn)O_x類化合物中存在大量的羧酸結(jié)構(gòu),推測(cè)含氮化合物可能來(lái)自于O_x類化合物的衍生反應(yīng)。實(shí)驗(yàn)結(jié)果拓寬了對(duì)地下水中可溶性有機(jī)質(zhì)的認(rèn)識(shí),為進(jìn)一步確定其中雜原子化合物的結(jié)構(gòu)類型奠定了基礎(chǔ)。
[Abstract]:The groundwater was analyzed by electrospray ionization source and Fourier transform ion cyclotron resonance mass spectrometry (ESI FT-ICR MS). Based on the results of high precision molecular weight detection, the large categories of OXX and N_2O_x3 were identified. A total of 27 small groups of compounds containing hetero atoms. The N-containing compounds are widely present in the form of a large number of oxygen atoms. Combined with the equivalent double bond number (DBE) and the carbon number distribution of various hetero-atomic compounds, it is found that there are a large number of carboxylic acids in the O _ x compounds. It is suggested that the nitrogen-containing compounds may be derived from the derivative reactions of O _ S _ x compounds. The experimental results broaden the understanding of soluble organic matter in groundwater and lay a foundation for further determining the structural types of hetero-atomic compounds.
