A 0.50 gm portion of this material is weighed with a precision torsion balance. Samples are digested in hot solution of HN03 and HC104 for three and half hours, then
Live ChatAn amorphous, homogeneous material with a random liquid like structure generally formed due to rapid cooling. Glasses can be natural rocktypes (such as obsidian, lechatelierite or tektite) or artificial materials (e.g., in slags).Most natural and artificial glasses are predominantly composed of silica with variable amounts of impurities, especially alkalis.
Live ChatIn this study, a total of 36 plant samples of 17 species was collected from 10 locations at the site. Concentrations of Pb, Cu and Zn in soils and plant biomass are provided in Table 2, Table 3, Table 4.Total Pb concentrations in the plants ranged from non detectable to as high as 1183 mg kg 1, with the maximum being in the roots of Phyla nodiflora from site 4 ().
Live ChatConcentrations of trace metals (Cd, Pb, Cu, Zn and Ni) were measured by the GF AAS method using instrument Perkin Elmer 1100 B. All equipment used for sample preparation and analysis was soaked in 0.1 M nitric acid for 24 h and then rinsed several times with Milli Q deionised water ([18 MX) prior to use. About 0.1 g of dried sediment
