本文使用带有模拟电子计算机自动转换浓度的GEW-170型光电直读光谱仪,以晶体管稳流直流电弧粉末法,研究了硅酸盐中锰、钛、钡、铬、锶、钒、铍、钴、镍九个元素的同时测定,认为使用碳粉、CuO、LiBO_2、K_2S_2O_7作缓冲剂,Cu为内标,保证了在积分时间内各元素平稳的蒸发,单位时间内分析线对的强度比很相近。单次测量变动系数除钒为±10.5％外,其余元素均在±10％以下。每人每个工作日可进行20个样品分析,如样品已处理好,每天可进行100个样品测定。
In this paper, GEW-170 photoelectric direct reading spectrometer with automatic conversion of concentration by analog electronic computer was used to study the effects of manganese, titanium, barium, chromium, strontium, vanadium, beryllium, cobalt , Nickel nine elements at the same time determination, that the use of carbon powder, CuO, LiBO_2, K_2S_2O_7 as a buffer, Cu as an internal standard to ensure the smooth evaporation of the elements within the integration time, the unit of time to analyze the intensity ratio of the line is very similar. In addition to the single measurement of variation coefficient of vanadium is ± 10.5%, the remaining elements are less than ± 10%. Each working day for 20 samples can be analyzed, such as the sample has been processed, 100 samples can be measured daily.
