“…In the acetic acid/acetate buffer (pH 2.6-4.4), the spectral characteristics are similar to those in the KHP/HCl buffer (pH 2.3-3.8); maximum absorption at 650 nm was observed, the same as previously reported [11].…”

“…A number of methods have been reported for yttrium determinations such as AAS [1], NAA [2], XRF [3], ICP-AES [4], HPLC [5], and luminescence [6]. Spectrophotometric methods have included various color reagents such as Alizarin S [7], 8-hydroxyquinoline [8], Arsenazo I [9], Arsenazo III [10,11], Xylenol orange-cetylpyridinium bromide [12], PAN [13], and PAR [14]. Attempts were made to adapt the batch Arsenazo III methods to a flow-injection analysis (FIA) procedure in order to obtain a rapid, simple, and economic method for the determination of yttrium.…”

We proposed a simple flow-injection spectrophotometric procedure for the determination of yttrium using Arsenazo III and optimized various conditions (pH for color formation and sample, buffer systems, Arsenazo III concentration, injection volume, flow-rate, and mixing coils). The calibration was linear at least up to 1 mgY/L, with a detection limit (3r) of 0.02 mgY/L, RSD of 0.8% (n ‫ס‬ 11 at 0.40 mgY/L). A throughput of 60 injections h‫1מ‬ can be achieved. The procedure was applied to ore leachates of reference materials and samples.

“…Two runs covered the time range 10-100 ms and the third covered the time range 20-1000 ms. The diffusion coefficient for each of the three runs was determined by each of three methods: (1) the least-squares slope of the i vs. 1/2 plot (Cottrell slope), (2) substitution of the average value of it1/2 for a given run (90-100 data points) into the Cottrell equation, and (3) the least-squares intercept of the it1/2 vs. t1/2 plot (method I in ref 7).…”

“…Comparison with other pioneering Y 3+ and Pb 2+ probes [62][63][64][65][66][67][68][69][70][71] Trace level determination of Y 3+ and Pb 2+ using Mo(VI) complexes (M1 and M2) by uorescence method is compared with available pioneering probes and presented in Tables S1 and S2, [62][63][64][65][66][67][68][69][70][71] (ESI). † A closer look reveals that some probes may have better LOD but the method either involves uorescence Scheme 2 Plausible sensing mechanism.…”

“…Only a very few reports on Y 3+ coordination chemistry/extraction are available. [46][47][48][49][50] A zinc porphyrin-CONHquinone dyad (ZnP-CONH-Q) has been reported by Fukuzumi et al for the detection of Y 3+ in toxic benzonitrile medium, having a very low association constant. 51 On the other hand, optical probes for selective detection of Pb 2+ are few and involve either metal-organic frameworks/rhodamine derivatives.…”
