Japan), at -30C for the assessment of lead, copper and zinc by the atomic absorption spectrophotometer (Perkin Elmer HGA 700-Germany), also for the estimation of serum iron on Hitachi 902 auto analyzer using Roche reagents kits.
The samples were analyzed under Flame Atomic Absorption Spectrophotometer (Z-8230) Polarized Zeeman atomic absorption spectrophotometer) and levels of lead (Pb), chromium (Cr), nickel (Ni), zinc (Zn), and copper (Cu) were determined at the respective wavelengths of 217, 357, 232, 214, and 324 nm respectively.
Samples were analyzed for heavy metal (Zn, Ni, Cr, Pb, and Cd) concentration through atomic absorption spectrophotometer (Perkin Elmer, AAS-PEA-700), and compared with World Health Organization (WHO) guideline values for drinking water.
1mL of the colloidal solution of prepared Cu NPS was diluted with 10 mL of the distilled water and then this diluted solution was aspirated into the atomic absorption spectrophotometer through capillary tube to confirm the NPs synthesis.
Concentrations of Cu and Zn were determined in fish samples by atomic absorption spectrophotometer. Highest Cu concentration of 4.52 +- 0.24 mg kg-1 wet weight was observed in muscles of M.
The preconcentration was followed in this sorption method and the concentrations were determined by atomic absorption spectrophotometer.
Soil samples were analyzed for macro and micronutrients including magnesium, copper, chromium, nickel, manganese, cobalt, lead, cadmium, sodium, iron, calcium, nitrogen, phosphorus and potassium by ammonium bicarbonate-diethylenetriaminepenta acetic acid (DTPA) method using atomic absorption spectrophotometer. Soil pH, moisture, clay, silt, sand, soluble salt and organic matters were determined using standard protocols.
UV-Vis absorption spectrophotometer (Shimatzu SP8001) was used to determined the surface plasmon resonance (SPR) of the colloidal.
The soil samples were investigated for trace heavy metals through Atomic Absorption Spectrophotometer.
