Assessment of heavy metal pollution from anthropogenic activities and remediation strategies: A review.
TL;DR: The concentration of heavy metals in several sites, assessed in water, soil and sediment samples, affected by different pollution sources are reviewed, showing how human activities impact natural media and how the pollution spreads.

Selective removals of heavy metals (Pb2+, Cu2+, and Cd2+) from wastewater by gelation with alginate for effective metal recovery
Fei Wang,Xingwen Lu,Xiao-yan Li +2 more
TL;DR: A novel method that uses the aqueous sodium alginate solution for direct gelation with metal ions is developed for effective removal and recovery of heavy metals from industrial wastewater and chemical analysis of the gels suggests that the gelation mainly occurred between the metal ions and the -COO(-) and -OH groups on alginates.

Kinetics of Adsorption on Carbon from Solution
Walter J. Weber,J. C. Morris +1 more
TL;DR: In this paper, it was shown that the rate of adsorption of persistent organic compounds on granular carbon is quite low and the rate is partially a function of the pore size distribution of the adsorbent, of the molecular size and configuration of the solute, and of the relative electrokinetic properties of adsorbate and adsorbents.
