Abstract

In the present paper, the physics property and nebulization character of the sample solution as well as elemental spectrum intensity were investigated with the prolonging of magnetization time after the water solution with the ethanol was magnetized under magnetic field of 0.24T. The magnetization mechanism was discussed. The experiment result shows that the efficient age-rate of the analyzed sample is increased. The peak values of the spectrum intensity appear when the ethanol is added into the sample. Under the magnetization time of 2 hours, the spectrum intensities of Zn, Pb, Cd, Fe, Si, Cu, Cr and Sr in the sample solution without the ethanol were increased by 22.9%, 38.8%, 25.6%, 48.3%, 52.4%, 6.0%, 22.3% and 22.7% than that with the non-magnetic water, respectively; The signal intensities of the elements in the sample solution with the ethanol of 6% were increased by 22.4%, 42.6%, 39.4%, 72.4%, 43.9%, 9.7%, 16.1% and 17.1% than that with the non-magnetic water, respectively. The detection limit of spectral analysis was reduced when the magnetized sample solution was analyzed.

摘要

本文研究了在0.24T磁场下对含有乙醇的水溶液进行磁化后，随着磁化时间延长，样品溶液的物理性质、雾化特性以及元素光谱强度，并探讨了磁化机理。实验结果表明，被分析样品的有效老化速率提高。当向样品中加入乙醇时，光谱强度出现峰值。在磁化2小时的情况下，不含乙醇的样品溶液中Zn、Pb、Cd、Fe、Si、Cu、Cr和Sr的光谱强度分别比非磁性水提高了22.9%、38.8%、25.6%、48.3%、52.4%、6.0%、22.3%和22.7%；含6%乙醇的样品溶液中各元素的信号强度分别比非磁性水提高了22.4%、42.6%、39.4%、72.4%、43.9%、9.7%、16.1%和17.1%。对磁化后的样品溶液进行光谱分析时，光谱分析的检测限降低。
