| Abstract | ||
| The paper deals with studying the effects of the experimental factors on the values of stability constants (K) of the dyes formed by the reactions of aromatic aldoximes as 2-hydroxybenakloxime, 2,4-dihydroxy benzaldoxime and 2-hydroxy-l-naphthaldoxime with diazotized sulfanilic acid salt. Experimentally, two physic; parameters have been founded to be effective on the value of K as the presence of three surface active reagents [cetylIrimethyl ammonium bromide (CTAB), sodium dodecyl sulphate (SDS), starch] and a four polar solvents (water, inethanol, ethanol, n-propanol). Generally, the stability constant alue of any dye formation is determined by knowing the structure of aldoxime, the dielectric constant of the me J mm, the type of surfactant and pl-1 under study. | ||
