In(CH2)6N4 buffer medium,the rapid color reaction of lead(Ⅲ)with methyl hymol blue(MTB)in the presence of ethanol forms a blue complex with a maximum absorption wavelength at 605nm.Under the optimal conditions,Beer's law is obeyed in the range of 0-10.0mg·L~(-1) for Pb(Ⅱ).The limit of detection is 0.2 mg·L~(-1).The results for the actual samples are satisfactory.
