Halite–crystals produced in solar salts Works of Sfax Saline (E.S of TUNISIA), more often, contain fluid inclusions which fill inter– and intra–crystalline cavities and represent from 3 to 5 % in mass. With the sole aim of quantifying the impact of fluid inclusions on chemical quality of NaCl...

Rice husk carbon (RHC) has the ability to adsorb the dyestuff from aqueous solution. It may be useful low cost adsorbent for the treatment of effluents, discharged from textile industries. The effectiveness of RHC have been tested for the removal of colour from the wastewater samples containing...

Anionic poly(sodium acrylate), PANa, hydrogels bearing negatively charged –COO- groups were used as sorbents for the removal of colored organic or inorganic model pollutants, namely Crystal Violet and Cu2+, from water. It was found that PANa hydrogels adsorb stronger Cu2+ions than Crystal Violet, as...

In coastal marine environments, with shallow, warm and calm waters, it is sometimes possible to observe the presence of organosedimentary structures that are commonly flat and laminar in shape. These structures are called algal mats or recent stromatolites due to their remarkable similarities to...
