Conductometric studies on the complexation properties of two newly synthesized lariat ethers viz 1,5-di(cyanoethane)-2,4 : 7,8 : 13,14-tribenzo-1,5-diaza-9,12-dioxacyclopentadeca-2,7,13-triene (L 1 ) and 1,5-di(cyanoethane)-2,3,4-pyridine-7,8 : 13,14-dibenzo-1,3,5-triaza-9,12-dioxa cyclopentadeca-2,7,13-triene (L 2 ) towards various metal ions in acetonitrile solutions revealed the formation of 1 : 1 ligand metal complexation. These compounds were explored as neutral ionophores for the fabrication of Nd 3þ selective and sensitive membrane coated graphite electrodes (CGEs). Among all the electrodes prepared, CGEs with membrane composition L 1 (5%) : NaTPB(3%) : NPOE (57%) : PVC (35%) and L 2 (5%) : NaTPB(3%) : NPOE (53%) : PVC (39%) showed best performance. Both the electrodes showed Nernstian response towards Nd 3þ ions over a wide concentration range with detection limits 3.8 Â 10 À8 mol L À1 and 1.6 Â 10 À8 mol L À1 respectively. These electrodes showed a fast response time of < 15 s and could be used over a period of three months without significant divergence in their characteristics. The proposed electrodes revealed very good selectivity for Nd 3þ ions over several ions. However, higher concentration of Co 2þ , La 3þ , Pr 3þ and Yb 3þ caused some interference. The potentiometric response of these electrodes was excellent in the range of pH 3.5 to 7.6 and they could tolerate up to 20% (v/v) nonaqueous media in the test solutions. These electrodes were used successfully as indicator electrode in the potentiometric titration of Nd 3þ against EDTA and also in the quantitative determination of Nd 3þ ions from binary mixtures and water samples.

“…The available methods for low-level determination of lanthanum and other lanthanide elements in solution include X-ray fluorescence [6], isotope dilution mass spectrometry [7], neutron activation analysis [8], ICP-MS [9], ICP-AES [10] and spectrophotometry [11]. However, these methods are either time consuming, involving sample manipulations or too expensive for most analytical laboratories.…”

“…Oligoelement determinations by ETV-ICP-MS are of increasing importance [1][2][3][4][5][6][7][8][9], because the ETV device reduces the polyatomic interferences of elements which are severely affected in conventional nebulization ICP-MS [6,[10][11][12][13]. The ETV generates dry, stable aerosols which are atomized and ionized in the second stage, i.e.…”

The operational parameters of the graphite furnace for electrothermal vaporization inductively coupled plasma mass spectrometry (ETV-ICP-MS), i.e. the internal carrier gas flow rate, the total carrier gas flow rate, the sample pretreatment temperature and the volatilization temperature, are optimized for oligoelement determinations ( 75 As, 9 Be, 112 Cd, 50 Cr, 65 Cu, 103 Rh, 123 Sb). The volatilization temperatures of As and Cr are compared to those obtained by graphite furnace atomic absorption spectrometry (GFAAS). Several modifiers Mg(NO 3 ) 2 , Pd(NO 3 ) 2 , Mg(NO 3 ) 2 /Pd(NO 3 ) 2 , Ni(NO 3 ) 2 , KI, (NH 4 )H 2 PO 4 have been tested using the concentrations recommended for GFAAS. The concentration of Mg(NO 3 ) 2 alone and in combination with NaCl has been varied to find the optimal modifier conditions. ETV-ICP-MS signal enhancements by a factor of 10 to 130 respective to those of conventional nebulization have been obtained. The optimized parameters are evaluated by analyzing the water standard reference NIST 1643c and the aqua regia solution of the lake sediment reference material BCR 280.
