Construction of 1, 10-phenanthroline functionalized magnetic starch as a lead (II) tagged surface imprinted biopolymer for highly selective targeting of toxic lead ions.

In this research 1, 10 - phenanthroline functionalized CaFeO - starch was employed as a magnetic ion-imprinted polymer (IIP) for highly selective targeting toxic Pb ions from aqueous media. VSM analysis revealed that the sorbent has magnetic saturation of 10 emu g which is appropriate for magnetic separation. Moreover, TEM analysis confirmed that the adsorbent is composed of particles with a mean diameter of 10 nm.

Toxic cadmium selective sequestration from food samples using melamine anchored magnetic cellulose by surface imprinting route.

Cadmium is very toxic for living organisms hence selective and efficient control capturing of it is necessary. To reach this goal a novel imprinted polymer was developed using melamine anchored MnFeO - cellulose. Magnetic cellulose was synthesized through an ultrasound-assisted precipitation route.

Molecular Identification of Species in (Diptera: Psychodidae) in Western Iran.

Background: Visceral and cutaneous leishmaniasis are common in some areas of Iran and consider as health problems. has been incriminated as a suspected vector for the both form of leishmaniasis.

Methods: This study was carried out in 4 western provinces of Iran.

Partitioning of α-lactalbumin and β-lactoglobulin in aqueous two-phase systems of polyvinylpyrrolidone and potassium phosphate.

In the present study, the partitioning of α-lactalbumin, β-lactoglobulin, and cheese whey proteins in aqueous two-phase system of polyvinylpyrrolidone-potassium phosphate is investigated. The partitioning of proteins in this system depends on the polymer and salt weight percents in feed, temperature, and pH. The orthogonal central composite design is used to study the effects of different parameters on partitioning of α-lactalbumin and β-lactoglobulin.
