Introduction: Cadmium is recognized worldwide as a toxic metal. In this study, Solvent-Assisted Dispersive Solid Phase Extraction (SA-DSPE) combined with Flame Atomic Absorption Spectrometry (FAAS), was used for determination of trace amounts of Cadmium (Cd-II)) in drinking water samples.

in this study, for the analysis of human urine samples, a novel method explained for the determination of celecoxib, a nonsteroidal anti-inflammatory drug (nsaid), using molecularly imprinted solid-phase extraction (mispe) coupled with high-performance liquid chromatography (hplc). the synthesis of the mip was performed by precipitation polymerization in methacrylic acid (maa), ethylene glycol ...

Sensitive and easy applicable analysis of Quercetin molecules was executed whereby solid phase extraction (SPE) molecular spectrophotometric determination. For the determination quercetin, an accurate, economical, time-saving a new environmentally friendly method has been developed with simple spectrophotometer device available in every laboratory. As solid-phase sorbent, polymer nanocomposite ...

phosalone, malathion and diazinon were analyzed in corn oil using solid phase extraction (spe)with lanthanum silicate as a new solid sorbent followed by gas chromatography with nitrogenphosphorus detection (gc-npd). the efficiency of different eluents (methanol, dichloromethane,ethyl acetate, dichloromethane — ethyl acetate (1:1) and ethyl acetate — methanol (1:1)) werecompared for elution of o...

Mercury (Hg) causes hazardous cumulative effects in humans; like central nervous system disorders,hypertension and chromosomal aberrations. Therefore, due to high toxicity and bioaccumulationfactor, mercury determination and speciation in human blood is very important. A sensitive,accurate, precise and inexpensive method was demonstrated for preconcentration and speciationof ultra-trace mercury...

A solid phase extraction procedure for simultaneous separation and preconcentration of traceamounts of Cu+2 ion from various real samples prior to its determination by flame atomicabsorption spectrometry has been developed. The proposed method is based on the utilization ofmultiwalled carbon nanotube in combination with Cupferron ligand as a solid phaseextractant. The influences of the analytic...

Experiments were conducted to determine the ability of a hydrated sodium calcium aluminosilicate (T-Bind) sorbent to reduce the toxicity of aflatoxins (AF) or T-2 toxin in male broiler chickens from day of hatch to 21 d of age. In Experiment 1, the sorbent was added at 0.250 or 0.375% to diets containing AF at 5 or T-2 toxin at 8 mg/kg of diet. When compared with controls, AF reduced BW gain b...
