| Abstract: | A new method for the determination of mercury in cutting fluid and machining process waste fluid by cold atomic absorption spectrometry coupled with direct sampling method was established.The caccuracy and precision of the direct determination method of mercury were reliable.The detection limit of the method was 0.07ng while the recovery was from 87.3% to 106.5%.This method solved the mercury losing problem in the handling process and reduced the analytical period obviously and could be applied to the direct determination of mercury in cutting fluid and machining process waste fluid with satisfactory results. |
