Fluoride removal from water using activated and MnO2-coated Tamarind Fruit (Tamarindus indica) shell: Batch and column studies

Defluoridation of Water Using Tamarind (Tamarindus Indica) Fruit Cover: Kinetics and Equilibrium Studies

“…This indicates that there is a possibility of ring cleavage. 37 A similar work was carried out by Sivasankar et al 32 for fluoride removal. The reduction in the peak intensities are observed in the spectra of treated TNFC before and after fluoride adsorption compared to virgin TNFC, which may be due to the deformation of the characteristic bands.…”

“…The successful and cost-effective removal of contaminants from wastewater, by adsorption techniques, demands the optimal operation of the adsorption units. Fluoride removal from water using activated and MnO 2 -coated tamarind fruit (Tamarindus indica) shell: Batch and column studies were studied by Sivasankar et al 32 Similarly, Sriramachari 33 and Maruthamuthu and Venkatanarayanareddy 34 reported the binding of fluoride by tamarind gel.…”

Defluoridation of Water Using Musa Ornata Husk Nano Hydroxyapatite-Alginate Biocomposite.

“…The solution of 0.1M HCl and 0.1M NaOH was used for pH adjustment. In isotherm studies, 100mL of different initial fluoride concentration (3,5,7,9,11 and 13mg/L) was stirred with 0.1g of biocomposite adsorbent dosage in a thermostat shaker in the temperature range of 301, 311 and 321K at neutral pH. The sorbent was separated and the fluoride concentration was analyzed.…”

Comments on “Fluoride removal from water using activated and MnO2-coated Tamarind Fruit (Tamarindus indica) shell: Batch and column studies”

“…Recently, Sivasankar et al [1] published the above-mentioned paper and it is undoubtedly a highly useful and informative reference for researchers working in this field of study. Additionally, it is also good to know that activated MnO 2 -coated tamarind fruit has the ability to remove the toxic element, fluoride, when it exists past its prescribed limit [2].…”

“…In the sorption dynamic section (Sections 4.1 and 4.3 of Ref. [1]), a simple Lagergren pseudo-first order kinetic model as well as an Elovich model was performed to explain the experimental equilibrium kinetic data. Also, in the adsorption analysis section (Section 5.1.2 of Ref.…”
