Synergistic Cloud Point Extraction Behavior of Aluminum(III) with 2-Methyl-8-quinolinol and 3,5-Dichlorophenol

Abstract

The cloud point extraction behavior of aluminum(III) with 8-quinolinol (HQ) or 2-methyl-8-quinolinol (HMQ) and Triton X-100 was investigated in the absence and presence of 3,5-dichlorophenol (Hdcp). Aluminum(III) was almost extracted with HQ and 4(v/v)% Triton X-100 above pH 5.0, but was not extracted with HMQ-Triton X-100. However, in the presence of Hdcp, it was almost quantitatively extracted with HMQ-Triton X-100. The synergistic effect of Hdcp on the extraction of aluminum(III) with HMQ and Triton X-100 may be caused by the formation of a mixed-ligand complex, Al(dcp)(MQ)2.

Determination of Trace Zinc in Water, Soil and Rabbit Blood Samples Using Cloud Point Extraction Coupled With Ultraviolet-Visible Spectrophotometry

“…(Ohashi, 2004;Ulusoy et al, 2012). Separation and preconcentration based on CPE have attracted considerable attention in the last few years mainly because those procedures can decrease or eliminate the use or generation of toxic substances.…”

A Facile Synthesis of 9,10-Dimethoxybenzo[6,7]- ox-epino[3,4-<i>b</i>]quinolin-13(6<i>H</i>)-one and Its Derivatives

“…In addition to the medicinal applications, quinolines have been employed in the study of bioorganic and bioorganometallic processes [12]. In addition, quinoline derivatives have been widely utilized as ligands for preparing metal complexes [13][14][15] and as useful materials for organic synthesis [16][17][18][19]. As a result, the synthesis of novel quinoline-fused compounds remains as an attractive topic in area of organic synthesis.…”

Separation/Preconcentration Methods for the Determination of Aluminum in Dialysate Solution and Scalp Hair Samples of Kidney Failure Patients

“…The complex matrix with high levels of salts and micronutrients in dialysate solution and scalp hair samples makes difficult to analyze trace levels of Al 3+ content, especially by SPF [24]. So, the interfering cations can be eliminated by using 8-hydroxyquinaldine, which forms chelates with most of the metal ions except Al 3+ , which was not complexed with 8-hydroxyquinaldine due to steric hindrance of methyl group at the 2-position of aromatic ring [25].…”
