摘要
利用石墨炉原子吸收光谱法测量PTA装置冷却循环水中的硅含量,主要包括对仪器的测量条件进行调试,从而找到最佳的仪器测量条件,研究测量过程中产生干扰及如何消除,并与分光光度测定硅进行比较,测定结果偏差很小,证明原子吸收法测定循环水中硅含量可行。
Using graphite furnace atomic absorption spectrometry to measure the silicon content in cooling cycle wa- ter ( CCW ) of PTA plant, mainly including adjusting the measuring conditions of the instrument to find the best measuring conditions, studying the interference in the measuring process and how to eliminate it, and comparing with the spectrophotometric determination of silicon, the results deviation is very small, proved that the atomic ab- sorption method for the determination of silicon content in circulating water is feasible.
