| Abstract: | In pH 850 ammoniacal
medium,a new spectrophotometric method for determination of Cu () with sodium
diethyl-dithiocarbamate at the presence of Triton X-100 was introduced. max is 420 nm, apparent
molar absorption coefficient is 11104 Lmol-1cm-1.Beer 's law is obeyed in range of 044 mgL-1The
method has been applied to steel samples and inorganic salt with satisfactory results. |
