Removing Sr(II) and Cs(I) from the Aqueous Phase Using Basil Seed and Elucidating the Adsorption Mechanism

Abstract

To confirm the capability and mechanisms of Sr(II) and Cs(I) adsorption from the aqueous phase using basil seed (BS), virgin BS, calcined BS (BS500 and BS1000), and enzymatically treated BS, namely Mannanase BGM (M-BS), Pectinase G (P-BS), Hemicellulase (H-BS), and Cellulase A (C-BS) was evaluated. The adsorption capabilities of Sr(II) and Cs(I) of various BS adsorbents were also evaluated. The quantity of Sr(II) and Cs(I) adsorbed onto BS was greater than that of BS500 or BS1000, suggesting that the physicochemical characteristics of the BS surface affected Sr(II) and Cs(I) removal from the aqueous phase. Furthermore, the quantity of Sr(II) and Cs(I) adsorbed onto virgin BS was greater than that of enzymatically treated BS, indicating that glucomannan or (1,4)-xylan in the cellulosic hydrocolloid of the BS strongly affected the adsorption capability of Cs(I) or Sr(II) (except for M-BS in Sr(II) adsorption). Our obtained results indicate that, as an adsorbent, BS was capable of removing Sr(II) and Cs(I) from the aqueous solution.

Assessment of Cd(II) adsorption capability and mechanism from aqueous phase using virgin and calcined lignin

“…In contrast, the signals of Lig600, Lig800, and Lig1000 were not detected because Lig600, Lig800, and Lig1000 were prepared as carbonaceous material from lignin by the calcination treatment under our experimental conditions. Previous studies have reported that the number of surface functional groups such as phenolic and carboxyl groups decreased upon carbonization at approximately 600 C (Yokoyama et al, 2008;Uematsu et al, 2020). Therefore, similar trends were observed herein.…”

In vitro removal of paraquat and diquat from aqueous media using raw and calcined basil seed

“…Therefore, the development of recycling technology for waste biomass is urgently needed. Previous studies have reported that waste biomass such as mangosteen, wheat bran, basil seed, and agriculture wastes showed the capacity to adsorb harmful substances such as mercury, chromium, strontium, cesium, molybdenum, and dyes from aqueous media (Ogata et al, 2018(Ogata et al, , 2020a(Ogata et al, , 2020bSivarama Krishna et al, 2014;Somasekhara Reddy et al, 2012;Uematsu et al, 2020). These results indicate that the conversion from waste biomass to an adsorbent is one of the most useful techniques for reducing these wastes.…”

“…Co., Ltd. (Japan), respectively. Calcined BS at 1000 C (BS1000) was prepared by the carbonization of BS (Uematsu et al, 2020). Paraquat dichloride standard (C 12 H 14 C l2 N 2 ) and diquat dibromide monohydrate standard (C 12 H 12 Br 2 N 2 H 2 O) were purchased from FUJIFILM Wako Pure Chemical Co., Japan.…”

“…Basil has been traditional used as a medicinal plant to treat ailments such as kidney malfunction (Simon et al, 1999). A previous study reported that basil seed had the capacity to adsorb strontium and cesium from aqueous media (Uematsu et al, 2020) indicating that the potential of basil seed as a waste-biomass material (adsorbent) for the removal of harmful chemicals. In addition, this report elucidated that the adsorption capacity of calcined basil seed was greater than that of virgin basil seed for harmful cation chemicals from aqueous phase.…”

Comparative Study of Cationic Dye Adsorption Using Industrial Latex Sludge with Sulfonate and Pyrolysis Treatment

“…Being effective and low-cost, the adsorption method is more feasible than other methods of water treatment, so adsorption is a promising and common way to remove dyes from aqueous effluents [11][12][13]. Currently, a large range of adsorbent materials based on solid waste have been researched for removing dyes from aqueous solutions, such as waste coffee grounds [14], olive cake waste [15], metal hydroxide sludge [16], waste coal gangue [17], paper mill sludge [18], waste cellulose fibers [19], tannery solid waste [20], oil shale [21].…”
