Long-term impact of biochar on the immobilisation of nickel (II) and zinc (II) and the revegetation of a contaminated site
A field remediation treatment was carried out to examine the long-term effect of biochar on the immobilisation of metals and the revegetation of a contaminated site in Castleford, UK. The extracted concentrations of nickel (Ni) (II) and zinc (Zn) (II) in the carbonic acid leaching tests were reduced...
