    Occurrence and removal characteristics of phthalate esters from bottled drinking water using silver modified roasted date pits حسب Alhaddad F.A.

    منشور في 2021
    "…The removal percentage was increased from 90 to 99% by increasing the temperature from 30 to 50��C and then decreased to 92.3% at 60��C. Conclusion: RODP was successfully used as an effective adsorbent for phthalate esters removal from drinking water. …"

    Collision/reaction cell ICP-MS with shielded torch and sector field ICP-MS for the simultaneous determination of selenium isotopes in biological matrices حسب Al-Saad, Khalid A.

    منشور في 2011
    "…The determinations of selenium isotopes in biological samples were performed using both inductively coupled plasma collision/reaction cell quadruple mass spectrometer (CRC-ICP-QMS) and inductively coupled plasma sector field mass spectrometers (SF-ICP-MS). To significantly decrease the argon-based interferences at m/z 74 (36Ar38Ar), 76 ( 38Ar38Ar, 40Ar36Ar), 78 ( 38Ar40Ar), and 80 (40Ar40Ar), the gas-flow rates of a helium and hydrogen mixture used in the collision cell were optimized to 1.0 mL/min H2 and 3.5 mL/min He. …"

    Enhancing the electrocoagulation process for harvesting marine microalgae (Tetraselmis sp.) using interdigitated electrodes حسب A. Khatib, Wardan

    منشور في 2021
    "…Through numerical investigation, the induction of dielectrophoretic force was confirmed in the new electrode array. In this study, 10 min electrolysis time was found to be sufficient to harvest 82.4% microalgae with 1 cm electrode distance and 50 mA/cm2 current density. …"

    CO2 Absorption Capacity and its Enthalpy of Absorption in Aqueous Blend of MDEA/Piperazine/Arginine حسب Talkhan, A.G.

    منشور في 2020
    "…CO2partial pressure was varied from 9 to 99 kPa while temperature ranged from 293 to 323 K in increment of 10 degrees. The experimental results showed that the solubility of CO2 decreased with increasing ARG ration in the mixture. …"

    Electrocoagulation treatment of reject brine effluent from Solvay process حسب Osman M.A.

    منشور في 2019
    "…When no current was applied, removal of the ions was insignificant. Applying a current density of 0.1167 A/cm2 increased the removal percentages of NH4+ and Cl– by 71.6% and 26.9%, respectively, which proved that the removal was due to electrocoagulation. …"
