用分批法和柱富集法研究了噻唑偶氮对苯二酚富集水中痕量Cu~(2+)。介绍了载带有TAH的硅胶的制备和它的性质、富集Cu~(2+)的条件及吸附容量等工作。用载带TAH的改性硅胶富集后,用TAH光度法测定痕量铜的下限可达ppb数量级。
The trace amount of Cu 2+ in water enriched with thiazole azo hydroquinone was studied by batch method and column enrichment method. The preparation and characterization of silica gel with TAH and the conditions of Cu 2+ enrichment and adsorption capacity were introduced. With TAH modified silica gel loaded with TAH photometric method for the determination of trace copper up to ppb orders of magnitude.
