Sensitive and selective spectrophotometric determination of aluminium with Chrome Fast Pure Blue B and cetyltrimethylammoniumbromide

Prognostic factors in patients with glioblastoma multiforme (clinical research)

“…Most of the commonly used reagents for the determination of aluminum in the literature do not have high sensitivity 11 or require some surfactants for the enhancement of selectivity and sensitivity. 12,13 During the last 20 years, many investigators have focused on the toxicity of aluminum to living systems. 14,15 Furthermore, aluminum is widely used as an antiperspirant in both cosmetic and pharmaceutical products.…”

Selective and sensitive spectrophotometric method for determination of sub-micro-molar amounts of aluminium ion

“…However, some of the problems of the method based on ECR are the serious interferences by Fe(III), Mn(II) and F − , which widely exist in environment samples, and its sensitivity is not high enough to determine low concentrations of Al 3+ ion. The characteristic performances of some spectrophotometric method for aluminium determination are presented in Table 1 [8,[12][13][14][15][16][17][18][19][20][21][22][23][24]. Application of micelles in analytical chemistry involves the beneficial alteration of metal ion-ligand complex spectral properties via surfactant association.…”

Spectrophotometric determination of aluminium and indium with 2,2′,3,4-tetrahydroxy-3′,5′-disulphoazobenzene

“…Many spectrophotometric methods have been proposed using various azo dyes and other chromogenic reagents such as aluminon, xylenol orange, stilbazo, chlorophosphonazo I, methylthymol blue, erichrome cyanine R, chrom azurol KS, pyrocatechol violet, 8-hydroxyquinoline and alizarine [31][32][33][34][35][36][37][38][39] of aluminium. However, most of these methods lack sensitivity or selectivity, the procedures are sometimes rather complicated because of the need for extraction to separate interfering ions or expensive surfactants.…”
