The discharge of heavy metals from industrial effluents into the environment is a major concern today due to its toxicity and persistence in the environment. The present work deals with the removal of heavy metals i.e. Copper, Chromium, Lead and Zinc ions from aqueous solutions using fins of Catla catla fish. The effect of varying conditions in aqueous solution like pH, contact time, temperature, initial metal concentration, turbidity and biosorbent dosage on the biosorption processes was studied. Further, the biosorbent was used to remove heavy metals from different industrial effluents. The percentage removal of heavy metal ions from the industrial effluents using fins of Catla catla fish as a biosorbent were found in the following range: Copper ions (32.95 -99.34 %), Chromium ions (26.64 -100 %), Lead ions (19.85 -56.06 %) and Zinc ions (30.01 -99.24 %). The heavy metal concentration in aqueous solutions was estimated using ICP-AES and the structural characteristics of the biosorbent was determined by using Fourier Transform Infrared Spectroscope (FT-IR) analysis. The adsorption isotherm studies were carried out using Freundlich and Langmuir isotherm models. It was observed that fins of Catla catla which is thrown from fish market as wastes, have the capacity to remove heavy metals from aqueous solution and hence it can be used to remove heavy metals from industrial effluents.

“…On the other hand, a maximum decrease of approximately 40% was observed for both Pb +2 and As(V) when OP was used. The overall removal efficiency decreased when the initial metal concentrations increased, which could be due to saturation at sorption sites on the surface of the adsorbent [20,55]. Finally, the relatively faster adsorption of Cu +2 and its higher removal percentage compared to Pb +2 and As(V) when using DPF could only be attributed to smaller ionic radii, which may diffuse more quickly through the adsorbent pores than the other metals.…”

In this study, date palm fibres and orange peel in both individual and hybrid forms were studied for the removal of copper, lead, and arsenic. Equilibrium was achieved after 150 minutes, and the highest and the lowest removal efficiencies were for Cu +2 and As(V), respectively. A slightly higher removal efficiency of metal ions using orange peel was observed, which could be due to the greater number of functional groups on the chemically pre-treated adsorbent. The highest removal was observed at pH 6, and the adsorption data exhibited a linear increase in metal removal capacity with increasing adsorbent concentrations from 0.1 to 2 g/L. A significantly higher removal efficiency was observed for a 45 µm particle size compared to larger particle sizes. Additionally, a 30-40% decrease in removal efficiencies was observed for all three heavy metal ions when using the date palm fibres or the hybrid adsorbent when the initial metal concentrations were increased from 20 to 80 mg/L. The Freundlich model agreed with the experimental data slightly better than the Langmuir model for both date palm fibres and the hybrid adsorbent. A pseudo second-order kinetic model better described the kinetic behaviour of As(V) adsorption on the investigated adsorbents. Date palm fibres exhibited exothermic adsorption, while both orange peel and the hybrid adsorbent displayed exothermic and endothermic reactions. Increased randomness at the solid-liquid interface was observed for all adsorbents, and the Gibbs free energy change values were negative, confirming the spontaneous nature of adsorption, which proceeded in the forward direction.

“…Annual worldwide production is about 2000 tons [18]. Algal biomass can be used as a biosorbent material because is available in large quantities, its processing is relatively cheap and have gives good performance at low cost [19]. The dried biomass has excellent capability to bind cations of chromium, copper, nickel, zinc and other micronutrients because the cell wall possesses functional groups (carboxyl, phosphoryl, amino, thiol, sulphydryl) potentially available for metal ions [14,20].…”

Abstract:The aim of the present work was to examine the effect of the application of Spirulina platensis post-extraction residues enriched with Zn(II), Mn(II), Cu(II) via biosorption as micronutrient fertilizer for the biofortification of maize grains with micronutrients in field tests. As a nominal dose 2.5 kg ha -1 of zinc, 1.0 kg ha -1 of manganese and 0.5 kg ha -1 of copper were applied. The preparation was applied also in higher doses (150%, 200%) to investigate agronomic biofortification of maize grains. In field trials, obtained grain yield (7.2 Mg ha -1 for Spirulina 100%) was higher than in control group (6.2 Mg ha -1 ) and commercial reference product (6.6 Mg ha -1 ). For the same dose of micronutrients, their bioavailability was higher for bio-preparations than for reference fertilizer. The highest content of micronutrients delivered to plants (2.15 mg kg -1 -Cu, 7.07 mg kg -1 -Mn, 29.0 mg kg -1 -Zn) was observed for maize grains fertilized with preparation of Spirulina 150%, which signifies that biofortified maize grain was obtained. Corn grains biofortified with micronutrients can be used as staple food or feed preventing from micronutrient malnutrition. The application of micronutrient biocomponents based on Spirulina biomass allows to manufacture a valuable fertilizer with bioavailable micronutrients.
