Finding the amount of nitrous oxide produced in the reaction between lead sulfide and nitric acid Lead(II) sulfide dissolves in excess nitric acid according to the equation below. Calculate the volume of NO(g)" style="position: relative;" tabindex="0" id="MathJax-Element-2-Frame" class="...
Calculated toxicities of the lead decreased in the order nitrate > carbonate > sulfide, the same order as the decrease in the solubility of the metal compounds used. The 7-day LC50 ... for the nitrate was 5,321 +/- 275 ug Pb/g of soil, and this did not change with time. The ...
For removal efficiency of metal ions with time. To find out the removal efficiency (in %) of Cr(VI) or Pb(II) at different interval of time, two different solutions of potassium chromate (10 ppm) and lead nitrate (10 ppm) were prepared separately using distilled water at normal...
Stock solution of Pb(II) was prepared by dissolving lead nitrate salt using de-ionized water for a concentration of 100ppm. The adsorption study was carried out via batch adsorption experiments to evaluate the effect of pH, contact time and initial concentration and dose on Pb(II) adsorption. ...
Moreover, 2-F-BA was found to be a topoisomerase (Topo) I and IIα dual inhibitor in cell-based and cell-free assays. A hypothetical mode of binding to the Topo I-DNA suggested a difference between the hydrogen bonding of BA and 2-F-BA to DNA. The antitumor effects of the natural...
We aimed (i) to assess the pollution of PTEs; (ii) to identify and appoint the potential pollution sources using Pb isotope fingerprinting and multivariate statistical analysis; (iii) to quantify the Pb contribution from the potential sources using stable isotope mixing models. 2. Materials and ...

A stock lead solution (1000 mg/1) was prepared from lead nitrate using double distilled water and was used to prepare test solutions. 558 S.S. Amritphale et al. Main Group Metal Chemistry Results and discussion The effects of different types of pyrophyllite samples, concentration of adsorbate...
On the basis of these analytical results using cluster analysis for grouping the samples on the bases of the similarity in chemical and isotopic content and the available data from the literature for lead ore deposits in the Balkan Peninsula, the geological origin of the investigated archaeological ...
