Author Information Genelyn G. Madjos  from the Institute of the  Department of Biological Sciences, College of Science and Mathematics, Western Mindanao State University, Zamboanga City, Philippines Journal Name Journal of Biodiversity and Environmental Sciences | JBES Abstract Nickel miningposed a serious environmental problem due to run-offs and tailings. To address this, current techniques include excavation, chemical stabilization and soil flushing, but these methods are costly and impractical. One of the ecologically accepted treatments is phytoremediation. With the capacity of Centella asiatica (gotu kola) to thrive in moist soils with domestic effluents, this present study sought to evaluate its phytoremediation potential by employing an experimental design with three replicates of: (a

Potentiality of spent tea waste charcoal has been determined as low cost adsorbent for the removal of heavy metals (Nickel and Chromium) from the waste water with the three fold objective of solid waste management for effective and green treatment of heavy metals’ highly contaminated effluent.
Iron nanoparticles doped tea waste charcoal (Fe-TWC) was synthesized and characterized using powder XRD, SEM and EDX. Synthesized Fe-TWC was found quite effective in removing high concentrations of Ni (II) and Cr (VI) from the simulated samples as well as actual industrial samples.
Adsorption data follows Langmuir adsorption and pseudo-second order kinetic model for both the metals. Thermodynamic parameters have also been assessed.
This study indicated that Fe-TWC can be used as an effective, low cost and environment friendly adsorbent for the treatment of electroplating waste effluent.

Let’s get some knowledge about this research.  Abstract Coastal area of East Java Sea has long been threatened by industrial source pollution, mangrove conversion into shrimp culture, over fishing, destructive fishing, sedimentation, and coastal settlement. Heavy-metal is probably the most threat that directly influ
