Chemical Modification of Activated Carbon and Its Application for Solid Phase Extraction of Copper(II) and Iron(III) Ions
Powder activated carbon surface (AC) was grinded and modified and altered procedure thorough a facile and easy chemical reaction to appearance of 2-((3silylpropylimino)1-methyl) phenol (AC- (SPIMP)). Subsequently, this novel sorbent efficiently applied for the extraction and preconcentration of some metal ions from real samples. Preliminary the influences of variables such as pH, amounts of rea...
متن کاملChemical Modification of Nanosilica Toward Dispersive Solid Phase Extraction of Trace Triazine Herbicides from Environmental Water Samples
An easy and fast pathway in preparation of organo-functionalized silica in nanosize range withphenyl-terminated group via co-condensation method is reported. Fourier transform infrared(FTIR) spectra confirmed the grafting process and scanning electron microscopy (SEM) imagecorroborated formation of nanosized material. Applicability of phenyl-modified nanosilica wasexamined as a sorbent in dispe...
متن کاملSolid phase protein chemical synthesis.
The chemical synthesis of peptides or small proteins is often an important step in many research projects and has stimulated the development of numerous chemical methodologies. The aim of this review is to give a substantial overview of the solid phase methods developed for the production or purification of polypeptides. The solid phase peptide synthesis (SPPS) technique has facilitated conside...
متن کاملModification of mineral trioxide aggregate. Physical and mechanical properties.
AIM To evaluate the physical and mechanical properties of two cements with a similar chemical composition to mineral trioxide aggregate and to attempt to improve their properties by producing a composite material. METHODOLOGY Two cement types were used: a mixture of calcium sulpho-aluminate cement and Portland cement (CSA) and calcium fluoro-aluminate cement (CFA) in conjunction with an admix...
متن کاملReactivity of parallel-stranded DNA to chemical modification reagents.
Four 25-nt long oligonucleotides containing dA and dT (D1, D2, D3, and D4) which are capable of forming parallel-stranded (ps) or antiparallel-stranded (aps) duplexes have been synthesized [Rippe, K., Ramsing, N. B., & Jovin, T. M. (1989) Biochemistry 28, 9536-9541]. In the present study, the OsO4-pyridine complex (Os,py), diethyl pyrocarbonate (DEPC), KMnO4, and the 1,10-phenanthroline-cuprous...
