synthetic dyes are among the most common contaminants of the environment. therefore, the aim of this study was investigation the removal of basic blue 41 (bb41) and methylene blue (mb) from industrial effluents by useing raw and modified rice stems. in this study raw and modified rice stems treated chemically with citric acid (ca) and were used to explore the potentiality of rice stems for remo...

classical xerogels are robust, inexpensive and nontoxic materials with low-ordered nanoporous structures. in water streams where the ph is higher than the point of zero charge, the surface of classical xerogels such as tetraethoxy orthosilan (teos) xerogel is negatively charged. it was assumed that a xerogel can work as a strong adsorbent for metal ions without further modification. therefore, ...

A lot of Researchers have addressed removing mercury as a pollutant from the wastewaters several industries. Heavy metals are being removed wastewater through adsorption on activated carbon, which is becoming additional popular. Although commercial carbon ideal adsorbent for elimination, its extensive usage limited because high cost, encouraging researchers to explore alternative effective and ...
