Solid-Phase Extraction of Cu(II) Using Polyurethane Foam and Eriochrome Black T as Ligand for its Determination in Waters by Flame Atomic Absorption Spectrometry
Este trabalho descreve o desenvolvimento de uma metodologia para a pré-concentração seletiva de Cu(II) usando espuma de poliuretano (PUF) como suporte e o negro de eriocromo T (EBT) como ligante. A extração quantitativa do Cu(II) foi obtida em um meio contendo 60 mg L de EBT e pH 1,5 (ajustado com solução de HCl). O tempo mínimo para extração do Cu(II) foi de 30 min quando 200 mg de PUF foram a...
متن کاملExtraction and Determination of Heavy Metals Using Silver Coated Magnetic Nanoparticles and Flame Atomic Absorption Spectrometry
A rapid, simple and sensitive magnetic solid phase extraction (MSPE) method was developed for the pre-concentration and determination of copper and cadmium ions. In this study, modified Fe3O4@Ag nanoparticles were synthesized and then ligand 2-isonicotinoyl hydrazine carbodithiolate (ITHCDT) was bonded to silver due to the formation of covalent bond of S-Ag. In this method, copper and cadmium i...
متن کاملPreconcentration of Lead in Sugar Samples by Solid Phase Extraction and Its Determination by Flame Atomic Absorption Spectrometry
A simple and sensitive solid phase extraction utilizing C18 filled cartridges incorporated with dithizone for preconcentration of lead and its subsequent determination by flame atomic absorption spectrometry (FAAS) was developed. Several parameters such as type, concentration and volume of eluent, pH of the sample solution, flow rate of extraction and volume of the sample were evaluated. The ef...
متن کاملDetermination of lead and cadmium in water samples by cloud point extraction prior to flame atomic absorption spectrometry determination
Pb and Cd in water samples were determined by cloud point extraction (CPE) with sodiumdiethyldithiocarbamate (DDTC) as the chelating agent and octylphenoxypolyethanl (Triton X-114) asthe surfactant prior to flame atomic absorption spectrometry (FAAS) determination. The main factorsof affecting the extraction and detection processes were optimized. The preconcentration of 10 mL ofstandard soluti...
متن کاملComparison of Modified Palladium Nanoparticles and Homemade Activated Carbon Derived from Medlar for Solid Phase Extraction of Metal Ions Prior to Their Flame Atomic Absorption Spectrometry Determination
This study focus on the preparation of two supports including activated carbon derived from medlar and Palladium nanoparticles loaded on activated carbon (Pd-NP-AC). Subsequently, both adsorbent modified with a novel Schiff base chelating agent and their potential applicability for determination of trace amounts of metal ions from aqueous solution has been investigated. The method is based on c...
