The Comparison of Optimum Conditions for Lead (Pb) Analysis Method using DITHIZONE and EDTA Complex in Seaweeds (Eucheuma spinosum)

Abstract The comparison of optimum conditions for lead (Pb) analytical method using dithizone and EDTA complexes in Eucheuma Spinosum (Eucheuma Sp.) was measured a standard addition method, where the solution Pb 2+ added to sample reduce noise. Additionally, UV-Vis spectrophotometer used with Spinosum, ions both were measured. Both first developed determine optimal pH that would measure level Spinosum. most favorable such measurement 8, at which activity stable, complex complex, regression value closer one than complex.
