DETERMINATION OF LAS BY METACHROMATIC METHOD IN SEAWATER AND RESERVOIR WATER
Istanbul Regional Hygenic Institute ,Zeytinburnu ,Istanbul, Turkey
Linear alkylbenzene sulfonate was determined usually by methylene blue active substances method (MBAS) in water at a-band of the dye. A metachromatic method is proposed for the determination of anion active substances using various dyes as methylene blue, azur I, Nile blue and toluidine blue at α- and β- bands. Similar results were obtained with MBAS and metachromatic method. Thus the proposed metachromatic method can be used as well as MBAS method.
