  • the use of superporous p 3 acrylamidopropyl trimethyl ammonium chloride cryogels for removal of toxic Arsenate anIons
    Journal of Environmental Management, 2015

    Abstract:

    Abstract Poly((3-Acrylamidopropyl)trimethylammonium chloride) (p(APTMACl)) cryogels were used as a superporous polymer network for the removal of toxic Arsenate anIons from an aqueous medium. The fast swelling in water, in about 7 s, was shown to be very useful leading to fast Arsenate adsorptIon by p(APTMACl) cryogels within 30 min in comparison to 12 h for bulk common p(APTMACl) hydrogels. A maximum adsorptIon capacity of about 120 (mg/g) Arsenate was obtained for p(APTMACl) cryogels. Both the Langmuir and Freundlich adsorptIon isotherms were applied for adsorptIon of Arsenate anIons by p(APTMACl) cryogels, and it was observed that the adsorptIon of Arsenate anIons by p(APTMACl) cryogels are represented better via Langmuir adsorptIon isotherm providing the R 2 value of 0.998. Furthermore, mag-p(APTMACl) cryogels were synthesized, and shown to be very useful in the fast removal of toxic Arsenate anIons. The mag-p(APTMACl) cryogels including the adsorbed Arsenate were removed by an externally applied magnetic field, with some reductIon in the Arsenate Ion adsorptIon capacity. It was also further demonstrated that p(APTMACl) cryogels can be reused in the adsorptIon of Arsenate 5 times from aqueous environments without significant loss of adsorptIon capacity, from 113.47 ± 9 to 102.67 ± 6 mg/g.

  • PreparatIon and properties of a new solid state Arsenate As(V) Ion selective electrode and its applicatIon.
    Talanta, 2015
    Co-Authors: Güler Somer, Ummihan Taskoparan Yilmaz, Şükrü Kalaycı
    Abstract:

    In this study a new solid-state Ion selective electrode which is easy to prepare and sensitive to Arsenate Ion concentratIon is prepared. The solid salts used in the electrode compositIon were Cu2S, Ag3AsO4 and Ag2S. The principal component of the electrode was Ag3AsO4. The measurements were made in constant Ionic strength using 0.1M NaNO3 and at room temperature. The potentiometric response of electrodes prepared in various compositIons was investigated against Arsenate Ion concentratIon. The highest slope was obtained with 40% Ag3AsO4, 30% Cu2S and 30% Ag2S. This electrode showed linear response for Arsenate Ion in the 10(-5)-10(-1) M concentratIon range. An analytically useful potential change occurred, from 1×10(-6) to 1×10(-1) M Arsenate. The slope of the linear portIon was about 19±2 mV/10-fold change in Arsenate concentratIon. The lifetime of the electrode was more than two years, when used at least 4-5 times a day, and the response time was about 20-30s depending on the concentratIon changes. The interference of most common Ions and the effect of pH (6-10) have been investigated. This electrode has been used for the determinatIon of Arsenate Ion in beer sample.
