It was found that non-ionic surfactant noticeably enhances the absorbance of the Al(III)-morin complex. Determination of submicrogram quantities of Al(III) ion at pH4.00 was made possible by the addition of triton X-100. Maximum absorption was obtained at wavelength of 425 nm, with the calculated molar absorptivity, ϵ, of 9.31 × 103 l.mol1.cm1. A linear calibration curve of 0.03 to 2.0 μg mL1 with the detection limit of 0.015 μg mL1 was attained for determination of Al(III) ion. The calculated relative standard deviation (r.s.d) was 2.2% for Al(III) ion quantified at 1.0 μg mL1. The influence of foreign ions towards the Al(III)-morin complex responses have been carried out too, with Cu(II), Zn(II) and Pb(III) were found to be the main interferences.en-USDetermination of aluminiumMetal complex-surfactant interactionMorinNon-ionic surfactantTriton X-100Effect of addition of non-ionic surfactant to the A2l(III)-morin complex in spectrophotometry determination of aqueous aluminum(III) [Kesan penambahan surfaktan tak-ionik kepada kompleks Al(III)-morin dalam penentuan aluminium (III) akues secara spektrofotometri]Sains Malays.Article180718144512
