“…Two further reports involved the analysis of green tea 65 and chamomile tea and coffee. 66 Both groups employed DSPE procedures for the initial sample preparation. For the analysis of green tea, Karlidag et al 65 used ZrNPs, prior to measurement of Se by slotted quartz tube FAAS while Saylan et al 66 prepared a Schiff base ligand from the reaction of 5-bromosalicylaldehyde and o -phenylenediamine to form a coordinate nickel complex.…”

“…Atomic absorption spectrophotometry was performed for Ni (II) at 232 nm, using a Thermo Fisher ® Solaar S4 atomic absorption spectrometer (Waltham, MA, EE.UU.) using a nickel hollow cathode lamp, by direct determination with the flame technique; the measurement had a detection limit of 0.05 mg/L [40]. The adsorption capacity (q e ) in the batch system was calculated by Equation (1), where C o is the initial solute concentration, C f is the final concentration after adsorption, m is the mass of adsorbent, and V is the volume of the solution.…”

Batch and Packed Bed Column Study for the Removal of Cr (VI) and Ni (II) Using Agro-Industrial Wastes

2021

The objective of this study was to prepare bio adsorbents from agro-industrial wastes from yam starch (YSR) and plantain (PSR) production for its use in the removal of Cr (VI) and Ni (II) in aqueous solution in batch and continuous packed-bed column systems. Bromatological analysis showed that the biomaterials are rich in cellulose, lignin, hemicellulose, and SEM micrographs that evidence a mesoporous structure characteristic of materials of lignocellulosic origin. FTIR evidenced functional groups such as hydroxyl, carbonyl, and methyl, possibly involved in the uptake of metal ions. EDS and FTIR analysis after adsorption confirmed that the retention of the metals on the surface of the adsorbent materials was successful. Cr (VI) and Ni (II) removal efficiencies above 80% were achieved using YSR and PSR in batch systems at the different conditions evaluated. The optimum conditions for removing Ni (II) on PSR were a bed height of 11.4 cm and a temperature of 33 °C, while for YSR, they were: 43 °C and 9 cm for temperature and bed height respectively. The variable with the most significant influence on the removal of Cr (VI) in a batch system on the two bio adsorbents was temperature. In contrast, the adsorbent dose and temperature are relevant factors for PSR Ni (II) removal. Therefore, the residues from the preparation of yam and plantain starch have high potential for removing heavy metals from wastewater and are presented as an alternative for their final disposal.

“…Some of these techniques are still unavailable in most laboratories due to its high cost of the instruments. Among these methods, the atomic absorption spectrophotometry (AAS) has been used as common method for metal ions determination due to its sensitivity, selectivity, and accuracy [18][19][20] .…”
