“…It was suggested that water-soluble fiber promotes gel formation under gastric/intestinal conditions and reduces absorption rates (Brownlee 2011). The exponential growth of industrial activities has intensified environmental pollution issues and the deterioration of different ecosystems with the accumulation and distribution of toxic metals (Daşbaşı et al 2015). It is well-recognized that trace amounts of toxic metals such as lead and cadmium have an adverse impact on brain, kidney, and reproductive system at low levels throughout the food chain, posing several serious health problems, including the impairment in intellectual functioning, infertility, miscarriage, and hypertension.…”

A 50 % increase in the content of water-soluble dietary fibers from carrot residues (CRSDF) was obtained by a novel blasting extrusion processing (BEP) with improved water holding capacity and oil retention capacity. A neutral polysaccharide (CRSDF-2) was successfully separated by a DEAE-52-cellulose column chromatography system. The results of high-performance liquid chromatography (HPLC) and gas chromatography (GC) showed that CRSDF-2 contained four sorts of monosaccharides: arabinose, xylose, glucose, and galactose with a molar ratio of 0.58:1.50:1.0:2.02. The average molecular weight of CRSDF-2 was estimated to be approximately 5.98 × 10 4 Da. Moreover, it was illustrated that CRSDF displayed a high cation-exchange capacity and a high adsorption capacity for Pb cation. Furthermore, CRSDF was capable of binding sodium deoxycholate sodium cholate, sodium deoxycholate, and sodium taurocholate. CRSDF could be potentially used as a promising ingredient in functional food and pharmaceutical industries.

“…11, the extraction recovery, regardless of volume, has almost the same efficiency rate when sample volume differs from 10 to 200 mL. The EF was calculated as the ratio of the highest sample volume (200 mL) to the final volume of solvent (3 mL) [38] and it is found to be 66 for the Pb(II) ions.…”

Determination of toxic lead ions at trace level using solid-based adsorbents has become of interest in recent years. In this work, a novel bio-adsorbent originating from papaya peel waste (PPw) and magnetic nanoparticles (Fe 3 O 4 ) was developed (Fe 3 O 4 /PPw). The new adsorbent was prepared using a one-pot green method and characterized by Fourier transform infrared, X-ray diffractometer, energy-dispersive X-ray spectroscopy and field emission scanning electron microscopy. The synthesized Fe 3 O 4 /PPw was used as a magnetic solid-phase extraction (MSPE) sorbent for extraction of lead ions from waste water prior to assessing by flame atomic absorption spectroscopy. The parameters influencing extraction recovery, including desorption solvent, solvent volume, sample volume, extraction time, desorption time, adsorbent dosage, salt effect and pH were optimized. A linear response for the MSPE method was achieved at concentrations from 10 to 100 ng mL −1 with a good coefficient of determination (R 2 = 0.9987). Detection limits and quantitation limit of the MSPE method were observed around 2 ng mL −1 and 6.6 ng mL −1, respectively. The intraday and interday precision (%RSD) was in the range 1.6 %-4.5 % and 2.3 %-7.4 %, respectively. The recovery amounts obtained were 91 % for tap water, 85.9 % for river water and 86 % for waste water. The synthesized adsorbent showed a minimum reusability of eight cycles without significant change in the lead determination. The results proved that the new bio-adsorbent (Fe 3 O 4 /PPw) is potentially capable to extract the Pb(II) from aqueous media under optimum conditions with a high extraction efficiency.

“…Flame atomic absorption spectrometry (FAAS) as widely usable, simple and inexpensive equipment mostly failed for direct evaluation and determination of the low level of metal ions content in environment sample with complex matrices [16][17][18][19][20][21]. Therefore, developed of an efficient sample preparation technique prior to monitoring of trace level of heavy metal ions from different environmental sample is highly required to simultaneously preconcentre and/or separate target ions.…”
