摘要Using carbon nanotubes(CNTs) as a toner, a novel, rapid and inexpensive spectrometric determination method for copper was developed in this work. Several factors affecting the absorbance of the coloration system, such as pH, kind of CNTs, concentration and addition order of reagents were investigated and optimized. The nature of the coloration system was also investigated. Comparative experiments prove that the absorption was increased by 74.1% due to the additing of CNTs into the coloration system. The calibration graph was linear in the range of 10-1100ng mL(-1) and the limit of quantification (10s) was 5.8ng mL.
