21. Solubility and Surface Complexation Studies of Apatites
Sammanfattning : Apatites are a diverse class of phosphate minerals that are important in a great variety of natural and industrial processes. They are, for example, used as raw material in fertiliser production and in the remediation of metal-contaminated soils. LÄS MER
22. Sustainable management of dredged sediments : potential recovery of valuable compounds
Sammanfattning : Dredging of sediments occurs worldwide to increase water depth in harbours, bays, lakes and rivers, as well as to recover aquatic ecosystems. Landfilling and open-ocean discharge are traditional disposal routes for dredged material. However, the methods are restricted by environmental and legal concerns. LÄS MER
23. Metals in MSWI fly ash - problems or opportunities?
Sammanfattning : Incineration of municipal solid waste is a commonly used management method to take care of our waste. However, the residues produced are a problem. They often contain large amounts of potentially toxic metal compounds and soluble salts, which can cause harm to the environment and human health if released from the ash. LÄS MER
24. Adsorption of Metallic Ions onto Chitosan : Equilibrium and Kinetic Studies
Sammanfattning : Equilibrium isotherms and the adsorption kinetics of heavy metals onto chitosan were studied experimentally. Chitosan, a biopolymer produced from crustacean shells, has applications in various areas, particularly in drinking water and wastewater treatment due to its ability to remove metallic ions from solutions.

25. Surface reactions in aqueous metal sulfide systems
Sammanfattning : Surface reactions in aqueous metal sulfide systems have been studied. The composition and stability of various complexes at the PbS-H20 the PbS/H20 and ZnS/H20 interface were evaluated. LÄS MER
