2020/8/8· In simpler terms, the equation states that a measured potential difference is proportional to the logarithm of the ion concentration. By measuring a nuer of solutions with known ionic concentrations, the relationships between potential and concentration can be easily plotted, making it possible to determine the concentration of an unknown substance using this data.

Sawdust (SD) a very low cost material has been utilized as adsorbent material for the removal of Cd (II) from aqueous solutions after treatment with mono methylol urea (MMU) in the presence of zinc chloride as a alyst to form MMU-SD. The reaction of MMU-SD
Metal toxicity to plants and transfer to food chain are related to metal bioavailability. In the present study, Pb and Cd have so the bioavailable content of them was estimated. The bioavailable lead content estimated in the roadside soil (Table 4 ; Figure 5 ) varies from 13.48 to 45.58 μ g/g.
Ethylene-propylene-diene terpolymer (EPDM)/wheat husk fibers (WHFs) composites were prepared using a laboratory size two-roll mill. Cure characteristics and some physical properties such as swelling, mechanical, and thermal properties of the vulcanizates were studied. The adhesion status between the WHF and rubber matrix is lacked in general, but it started to reinforce the matrix at higher
Name introduced in 1860 by Carl F. Rammelsberg, in his Handbuch der Mineralchemie.Here he reviewed some analysis of apatites, and found that apatite may have fluor(F) or chloride (Cl) as the dominant anion. An analysis of apatite from Kragerø, Norway (cited after Völker) showed 4.10 wt % Cl, and was named as chlorapatite.
