Wangl, K, J. Reddy, and L. C. Munn' Water Resources Center, University of Wyoming,Laramie, WY 82071 pBSTRACT: A variety of extractants has been used to assess the availability of molybdenum (Mo) in soils. Most of the extractants have been studied from a deficiency aspect rather than for soils with Mo toxicity, and none of them have been used to extract available Mo from mine spoils. The purpose of this study was to examine the potential of different chemical extractants for assessing the availability of Mo in mine spoils and soils. One mine spoil and three soils were treated with sodium molybdate and then subjected to wetting and drying cycles for two months. These spoiVsoils were extracted with ammonium bicarbonate DTPA (AB-DTPA), ammonium carbonate, and ammonium oxalate solution for available Mo. Crested wheatgrass (Agropyroncristatum) and alfalfa (Medicagosativa) were grown in the spoil/soils in a greenhouse to determine plant uptake of Mo. Additionally, four mine spoils and six soils were extracted and analyzed for available Mo as mentioned above.

    ISSN No. 2231-0045 VOL.II* ISSUE-IV*MAY-2014 Periodic Research Analytical Cupferron : A Micro-Analytical Reagent for Electrometric Estimation of Dysprosium & Terbium Abstract Cupferron, an ammonium salt of N Nitrosophynyl hydroxylamine [C H N (NO)ONH ] has been used as a reagent for the amperometric 6 5 4 3+ 3+ titration of Dy and Tb in very dilute solution using dropping mercury electrode. Hydrochloric acid (pH = 2.75 + 0.02) has been used as supporting electrolyte for the study of polarographic behaviour of cupferron. Cupferron gives a well defined cathodic wave in hydrochloric acid. The half wave potential varies with pH. The height of the diffusion current is proportional to the concentration of cupferron. The plateau potential of polarogram for cupferron, i.e. - 1.20 V Vs SCE was applied.

    EXPERIMENTAL INORGANIC CHEMISTRY For B.Sc. and M.Sc. Students As per new Syllabus Dr. M.K.Shah 2 Dedicated to all our beloved graduates & post graduate students 3 INORGANIC PREPARATION 4 1. TETRAMINE CUPRIC SULPHATE, [Cu(NH3)4 ]SO4H2O (A) REAGENTS Cupric sulphate, Ammonia, Ethyl alcohol, Nitric acid, Distilled water, Sulphuric acid. (B) REACTION CuSO45H2O(aq) + 4NH3(aq) [Cu (NH3)4]SO4H2O + 4H2O (C) PROCEDURE Take 5 gm crystalline cupric sulphate in a 250 ml beaker. Dissolve it in minimum quantity of water and then add few drops of diluted sulphuric acid. Add concentrated ammonia solution to the beaker with constant stirring, until the blue precipitate of cupric hydroxide, first formed completely dissolve to yield a clear, deep blue solution and there should be smell of ammonia in the beaker. Now add 20 ml alcohol dropwise from the dropping funnel to the beaker with constant stirring until the blue precipitates settled and clear solution is obtained. Heat it to 60o 70oC in the water bath for about 10-15 minutes. Then stop heating and remove the beaker from the water bath and allow it to stand. Long needle shaped blue crystals of tetramine cupric sulphate separates out. Filter and wash the crystals with a few drops of alcohol. Dry the crystals on a porous plate or in a desiccator. Weigh the dry crystal and find out the percentage yield followed by percentage purity by usual methods. 2. TRI (THIOUREA)-CUPROUS SULPHATE, [Cu (NH2CSNH2)3]2 SO4 2H2O] (A) REAGENTS Cupric sulphate, Ethyl alcohol, Nitric acid, Thiourea, Distilled water, Ammonia.
