“…Seeds or pods, or fruits used as an adsorbent Festus et al (2013) investigated on the flame of the forest (Delonix regia) tree pods for the sorption of lead and nickel ions from solution. The result showed that Delonix regia effectively removed these elements from aqueous solution, and equilibrium sorption of both metals was attained within 60 min-utes of interaction and 98% removed metals.…”

Wastewater pollution and its treatment is an ever-increasing concern in the century because of the higher industrialization and urbanization. The expansion of industries is the leading cause of polluting water resources. A discharge from industries contains various organic and inorganic pollutants. The heavy metals which are mostly discharged from the industries include Zinc (Zn), Arsenic (As), Nickel (Ni), Cadmium (Cd), Mercury (Hg), Copper (Co), Chromium (Cr), and Lead (Pb). These metals are toxic to human health and other living organisms. Water is an essential natural resource that reserves important flora and fauna on the earth. Therefore, it is necessary to remediate contaminated water from organic and inorganic pollutants. Chemical precipitation, ion exchange, reverse osmosis, chemical oxidation, reduction ultrafiltration, electrolysis, and adsorption are some treatment processes used to remove heavy metals from wastewater effluent. Adsorption is the most promising technique used for the removal of water pollutants. This review surveys the various natural adsorbents used to remove water pollutants. Natural adsorbents are the most effective and low-cost adsorption techniques in which plant residuals (leaves, stems, roots, straw, etc.) are used to remove water pollutants from wastewater.

Waste Material Recycling in the Circular Economy - Challenges and Developments

Activated carbon (AC) is a wonder-material that finds multifarious applications such as catalytic supports, removal of pollutants, electrodes in energy gadgets, gas storage etc. Surface area, chemical constituents and pore structures are a few traits required in the ACs which largely depend on the source of the precursors and processing methodologies adopted. In this context, the idea of recycling phytomass for producing ACs has attracted researchers seeing that the inexpensive and renewable nature of the phytomass can reduce the overall cost of producing ACs with diversified features and that it does not add CO2 to the atmosphere leading to global warming (plants release only the same amount of CO2 as they consumed while growing). Further, phytomass after their life possess no value but their conversion into ACs would be an economically profitable option leading to inexpensive ACs. As a consequent of these advantages this chapter has been planned and designed to provide certain interesting multifunctional aspects of low-cost phytomass derived ACs. The chapter is expected to provide research insights oriented towards identification of unexplored phytomass or wastes which could lead to carbon with novel properties tunable to the applications. Filth-to-wealth or in other words, recycling of wastes provides a strategy categorized under circular-bioeconomy, which is the want of the hour.

“…Wilson's and Alzheimer's diseases, mental illness, Indian childhood cirrhosis and schizophrenia are also reported to be caused by excess copper in the blood (Brewer, 2007;Faller, 2009;Hurean and Faller, 2009). Nickel has detrimental effects on human health, resulting in allergic dermatitis, immunologic urticaria, and immediate and delayed hypersensitivity (Festus et al, 2013). All nickel compounds, except for metallic nickel, have been classified as human carcinogens by the International Agency for Research on Cancer (IARC, 1990) and the U.S. Department of Health and Human Services (DHHS, 1994).…”

Abstract. In this study, the adsorption of Ni(II) and Cu(II) ions from aqueous solutions by powdered Delonix regia pods and leaves was investigated using batch adsorption techniques. The effects of operating conditions such as pH, contact time, adsorbent dosage, metal ion concentration and the presence of sodium ions interfering with the sorption process were investigated. The results obtained showed that equilibrium sorption was attained within 30 min of interaction, and an increase in the initial concentration of the adsorbate, pH and adsorbent dosage led to an increase in the amount of Ni(II) and Cu(II) ions adsorbed. The adsorption process followed the pseudo-second-order kinetic model for all metal ions' sorption. The equilibrium data fitted well with both the Langmuir and Freundlich isotherms; the monolayer adsorption capacity (Q0 mg g−1) of the Delonix regia pods and leaves was 5.88 and 5.77 mg g−1 for Ni(II) ions respectively and 9.12 and 9.01 mg g−1 for Cu(II) ions respectively. The efficiency of the powdered pods and leaves of Delonix regia with respect to the removal of Ni(II) and Cu(II) ions was greater than 80 %, except for the sorption of Ni(II) ions onto the leaves. The desorption study revealed that the percentage of metal ions recovered from the pods was higher than that recovered from the leaves at various nitric acid concentrations. This study proves that Delonix regia biomass, an agricultural waste product (“agro-waste”), could be used to remove Ni(II) and Cu(II) ions from aqueous solution.
