Preparation and characterization of zinc-exchanged montmorillonite and its effectiveness as aflatoxin B-1 adsorbent
(Elsevier Science Sa, Lausanne, 2012)
A zinc-exchanged montmorillonite (Zn-MONT) was prepared from a natural montmorillonite (MONT) and the adsorption of aflatoxin B-1 (AFB(1)) was investigated at pH 3 and 7. Characterization of Zn-MONT was done by determination ...
Mechanism of stearic acid adsorption to calcite
(Elsevier, Amsterdam, 2013)
This paper presents the interpretation of binding mechanism of stearic acid for calcite surface in two modification methods. In the "dry" method, a surface dissociation of stearic acid is assumed where H+ ion goes to a ...
Adsorption of the mycotoxin zearalenone by clinoptilolite and phillipsite zeolites treated with cetylpyridinium surfactant
(Elsevier, Amsterdam, 2017)
In this study, organozeolites were prepared by treatment of the natural zeolites (clinoptilolite and phillipsite) with cetylpyridinium chloride (CP) equivalent to 50 and 100% of their external cation exchange capacities ...
Adsorption of arsenic (V) by iron (III)-modified natural zeolitic tuff
(Springer Heidelberg, Heidelberg, 2009)
Adsorption of arsenic (V) by natural zeolitic tuff, modified with iron (III), was investigated. Also, the iron (III) adsorption characteristics by natural zeolitic tuff was evaluated. It was determined that iron (III) ...
Mechanism of adsorption of Cu2+ and Zn2+ on the corn silk (Zea mays L.)
(Elsevier, Amsterdam, 2017)
In this study the novel biosorbent - raw corn silk (CS) was investigated for Cu2+ and Zn2+ removal from aqueous solutions. The physical and chemical properties of CS were determined by SEM - EDX and ATR - FTIR techniques. ...
Efficient mercury removal from wastewater by pistachio wood wastes-derived activated carbon prepared by chemical activation using a novel activating agent
(Academic Press Ltd- Elsevier Science Ltd, London, 2018)
Ammonium nitrate (NH4NO3) with explosive characteristics at high temperatures was used as a novel activating reagent to prepare a surface-engineered activated carbon derived from pistachio wood wastes (PWAC). PWAC was ...
In situ synthesis of potassium tungstophosphate supported on BEA zeolite and perspective application for pesticide removal
(Science Press, Beijing, 2019)
Potassium tungstophosphate is supported on BEA zeolite by in situ synthesis for glyphosate removal. Spectroscopic measurements identified hydrogen bonding as a primal interaction of potassium salt and BEA zeolite. Composites ...
Removal of Pb2+ ions by raw corn silk (Zea mays L.) as a novel biosorbent
(Elsevier, Amsterdam, 2016)
There is no data about the corn silk usage as adsorbent for lead removal. In the present study, the corn silk (CS), without any modification, was investigated for adsorption of Pb2+ ions from aqueous solutions. The CS ...
The adsorption of salicylic acid, acetylsalicylic acid and atenolol from aqueous solutions onto natural zeolites and clays: Clinoptilolite, bentonite and kaolin
(Elsevier, Amsterdam, 2013)
In this study, adsorption of salicylic acid, acetylsalicylic acid and atenolol from aqueous solutions onto clinoptilolite modified with sorbed metallic cations (Cu(II), Zn(II), Ni(II) or Mn(II)) have been probed. Natural ...
Investigation of adsorption and release of diclofenac sodium by modified zeolites composites
(Elsevier Science Bv, Amsterdam, 2013)
Results on adsorption of diclofenac sodium (DS) by modified natural zeolite composites at three levels (10,20 and 30 mmol/100 g) of cationic surfactant-hexadecyltrimethylammonium bromide (HB), in a buffer solution, were ...
