Seawater ultrafiltration: role of particles on organic rejections and permeate fluxes.
Environ. Technol. 34(17-20) , 2553-61, (2013) The role of natural compounds of seawater and added particles on mechanisms of membrane fouling and organic matter rejection has been investigated. Ultrafiltration (100 kDa) has been conducted in both dead-end (out/in) and tangential (in/out) modes on polysul... |

Bisphenol A sorption by organo-montmorillonite: implications for the removal of organic contaminants from water.
Chemosphere 107 , 249-56, (2014) Remediation of bisphenol A (BPA) from aqueous solutions by adsorption using organoclays synthesized from montmorillonite (MMT) with different types of organic surfactant molecules was demonstrated. High adsorption capacities of the organoclays for the uptake ... |

Non-selective oxidation of humic acid in heterogeneous aqueous systems: a comparative investigation on the effect of clay minerals.
Environ. Technol. 35(17-20) , 2389-400, (2014) Application of photocatalysis for degradation of natural organic matter (NOM) has received wide interest during the last decades. Besides NOM, model compounds more specifically humic acids (HAs) were also studied. As a continuation of the previous research, T... |

Clarification of olive mill and winery wastewater by means of clay-polymer nanocomposites.
Sci. Total Environ. 442 , 134-42, (2013) Highly polluted effluents from olive mills and wineries, among others, are unsuitable for discharge into standard sewage-treatment plants due to the large amounts of organic and suspended matter. Efficiency of all management practices for such effluents depen... |

Hydraulic conductivity of compacted soils controlled by microbial activity.
Environ. Technol. 35(13-16) , 1886-92, (2014) The hydraulic conductivity defines the displacement of liquids inside porous media and affects the fate and transport of contaminants in the environment. In this research the influence of microbial growth and decay inside soil pores on hydraulic conductivity ... |

Attenuation of heavy metals by geosynthetics in the coal gangue-filled columns.
Environ. Technol. 34(17-20) , 2889-95, (2013) In the subsided areas backfilled with coal gangue, an issue of continuing environmental concern is the migration of hazardous metals to the subsurface soil and groundwater. As an effective isolation material, geosynthetics have been scarcely applied into mini... |

Changes in permeability and in mechanical properties of layer-by-layer films made from poly(allylamine) and montmorillonite postmodified upon reaction with dopamine.
Biointerphases 7(1-4) , 59, (2012) Polyelectrolyte multilayer (PEM) films present a versatile surface functionalization method allowing to address many applications. These coatings suffer; however, from weak mechanical properties this problem can be addressed by the regular incorporation of cl... |

Adsorption-desorption behavior of 2,4-D on NCP-modified bentonite and zeolite: implications for slow-release herbicide formulations.
Chemosphere 90(2) , 699-705, (2013) Clay minerals have obtained considerable attention for slow-release formulation of herbicides to increase weed control efficacy and reduce leaching potential and environmental pollution. This study deals with preparing, characterizing and examining the potent... |

Interstratification patterns from the pH-dependent intercalation of a tetracycline antibiotic within montmorillonite layers.
Langmuir 29(14) , 4492-501, (2013) Little is known about the distribution of the intercalated molecules within the interstratified layers resulting from the pH-dependent interlayer adsorption of ionizable organic molecules, including antibiotics, within smectite-type clay minerals. Here we emp... |

A review on zinc and nickel adsorption on natural and modified zeolite, bentonite and vermiculite: examination of process parameters, kinetics and isotherms.
J. Hazard. Mater. 252-253 , 428-61, (2013) Adsorption and ion exchange can be effectively employed for the treatment of metal-contaminated wastewater streams. The use of low-cost materials as sorbents increases the competitive advantage of the process. Natural and modified minerals have been extensive... |
