Acid generation and heavy metal leachability from waste lignite disposal sites, Oropos basin, North Attica. An assessment on preliminary data

Kampouroglou E., Kollias K., (Corresponding) Stouraiti C., Papassiopi N.
Topic: 
Heavy metals in the environment
Lignite mining in the Oropos Neogene basin (North Attica), especially in the areas of Milesi and Markopoulo, operated since last century and ceased in the late 1960’s. Piles of complex waste material consisting of lignite tailings and waste rocks are dispersed in the area between the above...Read more

Synthesis of kaolin supported nZVI and evaluation for the removal of Cr(VI) and Ni from waste streams

(Corresponding) Toli A., Mystrioti C., Della A., Thymi S., Papassiopi N.
Topic: 
Efficient water resources management in cr(vi) impacted water bodies
This study involved the synthesis of kaolin-supported nano zero valent iron (K-nZVI) and the evaluation of its performance for the removal of chromates and nickel from contaminated waters. K-nZVI was prepared by mixing a kaolin sample with a FeCl3 solution, followed by the addition of sodium...Read more

Application of Ni loaded FAU zeolites in catalytic conversion of 1,2-dichloroethane towards value added products

(Corresponding) Góra-Marek K., (Corresponding) Srębowata A., Kowalewski E., (Corresponding) Tarach K., Pyra K.
Topic: 
Nanomaterials in the environmnents applications and effects
The catalytic performance of nickel loaded zeolite materials was found to be dependent on their acidic feature that influenced metal speciation and its dispersion. The selectivity to ethane and ethane of the Ni loaded catalysts increased when reducing both the number of acid sites and average...Read more

Zinc and Nickel Accumulation in Unicellular Photosynthetic Algae Chlamydomonas reinhardtii Grown in Metal-contaminated Media

Zkeri E., Mavrakis E., Pergantis S., (Corresponding) Lydakis-Simantiris N.
Topic: 
Heavy metals in the environment
In this study, Zn and Ni accumulation in unicellular freshwater migroalga Chlamydomonas reinhardtii was investigated. C. reinhardtii cells were grown in media polluted with several concentrations of either Zn or Ni. Tolerance of this organism to Zn and Ni pollution was examined and the growth...Read more
