Application of mango seed integuments as bio-adsorbent in lead removal from industrial effluent

Utilization of biological waste in treatment of industrial effluents is an emerging field of research. In present context of waste management, bio-adsorbent-based techniques are wellestablished as inexpensive and eco-friendly approach for cleaning up contaminated effluents from various industries and as a part of sustainable process developments. Mango seed integuments have been used in this study as biological waste. The main objective of this study was based on the removal of heavy metal lead (Pb) (II) from paint industry effluent using the mango seed integuments. Efficiency of the process was optimized with variation of the process parameters such as adsorbent dosage, contact time, initial [Pb(II)] concentration, and adsorbent nature. The nature of adsorption was also assessed using standard isotherms. This work showed the potential of the mango seed integuments as bio-adsorbent for removal of lead ions from paint industry effluent.
