The following conclusions can be drawn from the batch scale laboratory studies. As the dosage of mushroom was increased, the removal efficiency also was found to increase. The initial heavy metal concentration was found to share an inverse relationship with percentage removal, which also was found to be greater at the initial stages of adsorption, and reducing gradually as contact time elapsed. Removal process as a function of stirring time was found to be more efficient than under steady-state conditions.
Under optimal conditions, the maximum percentage removal of Cu2+ was found to be 48.50%. The removal efficiency when compared to chemical techniques may be low; however the process is cost-effective and has no toxic by-products. As in the ecological context, copper also performs the role of micronutrients, the present study focused merely on encapsulation of Cu2+ using milky white mushroom as a matrix. This upon decomposition may be used in nature to contribute to the fertility value and thereby the study projects a completely exhaustive process.
SCOPE OF FUTURE STUDY
On basis of the removal efficiency, studies can also be carried on to ascertain the sludge fertility value. Synthesised wastewater was investigated in the current study. Future studies can involve industrial samples as well. As a future outlook, the native wild species Lactarius volemus can be substituted in the study and investigated. Future studies can include other heavy metals that also ecologically behave as micro-nutrients.
