Copper sorption in clay fractions of alluvial soils
TL;DR: The influence of copper sorption by iron hydroxides with different degrees of crystallization in clay fractions of several alluvial cultivated soils of the fertile lowlands of the Manzanares river (Madrid) has been studied.

Removal of ametryn from aqueous solutions with zeolite nanoparticles optimized using the box-behnken design
Mohammad Javad Khodayar,Fahime Namdar,S. Hojati,Ahmad Landi,Zahra Nazari Khorasgani,S. Alamolhoda +5 more
TL;DR: In this paper, the authors used the box-behnken design (BBD) of response surface methodology (RSM) for simultaneous optimization of all parameters affecting the adsorption process, including pH (6 - 8), the amount of adsorbent (0.5 - 2 g) and temperature (25 - 45°C).

Intrusions of dust and iberulites in Granada basin (Southern Iberian Peninsula). Genesis and formation of atmospheric iberulites
J. Párraga,Juan Manuel Martín-García,Gabriel Delgado,Alberto Molinero-García,Ana Cervera-Mata,I. Guerra,María Virginia Fernández-González,F.J. Martín-Rodríguez,Hassan Lyamani,Juan Andrés Casquero-Vera,A. Valenzuela,F.J. Olmo,R. Delgado +12 more
TL;DR: The role of bacteria and its polymeric exudates in the iberulite genesis has not been described previously, and it would explain the flux, transport and survival of tropospheric microorganisms over long distances as mentioned in this paper.

Geochemical and Mineralogical Characters of the Coastal Plain Sediments of the Arabian Gulf, Kuwait
TL;DR: In this paper, detailed geochemical and mineralogical studies of the coastal plain sediments formed along the shoreline of the Arabian Gulf area, Kuwait, were conducted and the results showed that the sand composed, on average of about 90% sand, and about 10% or less is mud, and has a unimodal distribution with a mode of medium sand.
