| Abstract: | A method for the determination of trace aluminum with ternary complex of Al-CAS-CTMAB is reported.The molar absorptivity is 8.1×10^4 L/（mol·cm） at 655 nm.Beer＇s law is obeyed in the concentration range of 0.02-0.4ug/mL.This method was simple,rapid,and sensitive when traced aluminum is determined. |
