Malachite green (MG) and Crystal Violet (CV) are used mainly as dyestuff and antimicrobials in aquaculture. They have a severe toxic effect on the environment. Several techniques were used to remove impurities from an aqueous solution: chemical, physical, and electrical. Among all these techniques...

The biosorption of uranium ions was explored through batch studies employing activated biochar derived from Gracilaria Edulis seaweeds. A chemical synthesis approach utilizing concentrated sulfuric acid created and activated the adsorbent material. SEM and FTIR measurements were used to characterize...
