PHASE 3: ENVIRONMENTAL BEHAVIOUR OF SLAGS (E.G. SOIL ENVIRONMENT)
EXPERIMENT 3: Effect of various organic acids (i.e. humic acid,
fulvic acid, artificial root exudates) on metals (Cu, Zn, Pb, Cd)
leaching from slags. Batch leaching experiments under slags
exposure to organic acids (24 h, 48 h, 72 h, 168 h, 960 h)
To present leaching trends
To indicate the most influential organic solution on
metals mobilization
pH meter
ICP-MS
PHASE 4: BIO-WEATHERING
EXPERIMENT 4: Bio-weathering behaviour of two types of Cu-
slags with bacteria Pseudomonas aeruginosa
To examine the role of Pseudomonas aeruginosa on the
weathering of Cu-slags exhibiting different chemical
and structural properties
pH meter
Spectrophotometer
ICP-MS
SEM
3D fluorescence
