“…UV-Vis spectrophotometric methods have been widely used due to simplicity, rapidity, low costs and wide applications [23][24][25][26]. For this purpose, widely-used chromogenic reagents are pyrocatechol violet [27], alizarin red S [28][29][30], arsenazo I and III [27][28][29][30][31], xylenol orange [21,[34][35][36][37], Janus Green dye [38], 2,4-dinitrophenol-(6-azo-2)-1-napthol-3,8-disulphonic acid (picramine <epsilon>) [39], 2-(6-bromo-2-benothiaoylazo) 5-diethylaminophenol and sodium lauryl sulphate [40], 4-(2-pyridiylazo) resorcinol (PAR) [41,42], 2-(5-bromo-2-pyridylazo)-5-(diethylamino)phenol [43], 5,7-dibromo-8-hydroxylquinoline [44], chorme azurol S [45], for determination of Zr(IV) by spectrophotometry was reported. Some methods have low sensitivity and selectivity and others have high sensitivity but low selectivity.…”

Solid-phase spectrophotometry was applied to determine trace amounts of zirconium(IV) in water, soil, plant materials and ore samples. Zr(VI) was sorbed in a dextran type lipophilic gel as a complex with 2-(2-benzothiazolylazo)-3-hydroxyphenol (BTAHP). Resin phase absorbances at 569 and 800 nm were measured directly, which allowed the determination of Zr in the range of 0.25-3.7 μg L −1 with an RSD of 1.06%. The influences of analytical parameters including pH, amounts of BTAHP, and sample volume were investigated. The molar absorptivities were found to be 1.08 × 10 5 , 6.38 × 10 6 , and 1.97 × 10 7 L mol −1 cm −1 for 100, 500, and 1000 mL, respectively. The LOD and LOQ of the 500 mL sample method were 150 and 470 ng L −1 , respectively, when using 40 mg dextran type lipophilic gel. For a 1000 mL sample, the LOD and LOQ were 80 and 240 ng L −1 , respectively. Increasing the sample volume enhanced the sensitivity. No considerable interferences were observed from other investigated anions and cations on the Zr(IV) determination.

“…Spectrophotometric methods occupy special position due to their simplicity, less expensive instrumentation and high sensitivity. Many methods of zirconium determination have been published [1,[3][4][5][6][14][15][16][17]. However, some of these methods have both low sensitivity and low selectivity while others have high sensitivity but low selectivity in presence of some ions or molecules.…”

A rapid, simple, selective, and sensitive method for trace determination of Zr (IV) has been developed based on the reaction of 1,4-dichloro-2,5-dihydroxyquinone in a hydrochloric acid medium to form a colored complex which is rendered water soluble by the micellar action of cetylpyridinium chloride (CPC) and measured at λmax 331 nm. Beer's law is obeyed in the concentration range 0-5 µg.ml -1 . The molar absorptivity of the complex, є was found to be 1.6 ×10 4 L.mol -1 cm -1 and Sandell's sensitivity was found to be 5.7 ng.cm -2 . A method for determination of Zr (IV) by second derivative spectrophtometry has also been proposed. The detection limit of Zr (IV) in the derivative method is 6 times lower than that of the zero order method, which shows the higher sensitivity of the derivative method. The method has been applied for determination of Zr (IV) in various samples, and satisfactory results have been obtained.
