In this work, low-cost and readily available limestone was converted into nanolimestone chitosan and mixed with alginate powder and precipitate to form a triple nanocomposite, namely limestone—chitosan–alginate (NLS/Cs/Alg.), which was used as an adsorbent for the removal of brilliant green (BG) and Congo red (CR) dyes in aqueous solutions. The …
Non-stop pollution for millenia Fuelled by rainfall, there is a non-stop flow of water contaminated with acid and heavy metals from the mine. And no solution in sight to stop the pollution. A common problem Acid that drains from mines is a very common problem in mining. It is also one of mining's most severe and important environmental challenges.
