“…The presence of different elements in the investigated adsorbents maybe is due to their presence in the soil, where the sugar beet was grown or they can originate from the equipment and chemicals used in sugar or bioethanol production process. Hassan et al (15) also reported presence of iron, copper and nickel in the sugar beet pulp determined by EDS. Witek-Krowiak and Reddy (16) reported that the EDS spectrum of soybean meal contained peaks of phosphorus, potassium and magnesium as the result of X-ray emission from the isoflavanoids/carbohydrate/cellulose present in the cell wall.…”

When biomaterials are used as adsorbents, some compounds present in their structure can be extracted and cause secondary pollution of the treated water. Depending on the type and amount of the secondary pollution, some materials can be unacceptable as adsorbents despite of their good adsorption capacity. Although, it is not a newly discovered phenomenon and it is recognized as a problem, leaching from adsorbents is neglected. The aim of our study is to investigate the secondary pollution of the water during the biosorption of heavy metal ions by pristine and modified sugar beet shreds from bioethanol production. The presence of different elements in the mentioned adsorbents, secondary pollution of the water during the adsorption of heavy metal ions and amount of reducing sugars in the water treated by pristine sugar beet shreds were characterized by the SEM-EDS method, the amount of the leached inorganic and organic matter from the adsorbents (atomic absorption spectroscopy and permanganate index) and Bertrand's method, respectively. Furthermore, the obtained results were compared to the available literature data. Our results showed that according to the valid regulations of emission limit values of the polluting substances in the water and adsorption capacity, the investigated adsorbents have a great potential as biosorbents for practical treatment of wastewaters which contain high concentrations of heavy metal ions.

“…While, the peak observed around 1716.1 cm −1 is attributed to the stretching vibration of bond carboxyl groups that may be indicate the carboxylic acids or their esters. Also, The peak observed at 111.7 cm −1 is due to C-H in plane [66,69]. In addition, the persisting of O-containing groups of carbons can serve as Lewis-acids, which can play a good route in adsorption mechanism [49].…”

Purpose Two types of active acidic alumina derived from aluminum building wire scraps (AlBWS) and aluminum takeout food container waste (AlTFC), as well, two effective types of activated carbon prepared from potato peels (ACPP) and sugarcane bagasse (ACSB) for removal of nitrate ions were utilized in this study. Methods Adsorbent samples were prepared with highly porous structure and large specific surface area above 200 m 2 g −1. Also, low calcinations temperatures and low-priced chemicals were used. Results The results showed that the adsorption of nitrates were rapid. The q max were found to be 12.4, 8.8, 7.1 and 3.9 (mg g −1) for AlTFC, AlBWS, ACPP and ACSB samples, respectively. The thermodynamic parameters showed the endothermic nature and adsorption of nitrate ions and are considered chemisorption. The total cost of the samples production were 13 USD kg −1 for acidic alumina and 6 USD kg −1 for active carbon. Conclusion The adsorption of nitrates were utilized in real and synthetic samples which give an excellent removing capability for nitrate pollution from groundwater samples.

“…Adsorption through ion exchange is an efficient method of removing several oxyanions because adsorbents can be regenerated and reused [14]. The adsorbents, which are also natural resins, applied by the research institute, are modified zeolites with the addition of H 2 SO 4 [15], amine group quartermodified chitosan beads [14] and alloy Zr(IV) with sugar beet pulp [16]. Synthetic resins used in nitrate and nitrite removal are strong base anion exchange resins with considerable adsorption capacity, such as ion-exchange resin Dowex 21K XLT with modified ferrous metals [17], Purolite A100 [18], Purolite A520E [19][20], A-250 IXR [21], Purolite A300 [20] and Indion NSSR [22].…”

“…Reference [17] showed Fe impregnation in Dowex 21K XLT resin and obtained maximum nitrate adsorption capacities of 27.6 and 75.3 mg N/g in Dowex and Dowex-Fe. Metal impregnation has also been conducted on resins and natural adsorbents, such as Zr(IV) in sugar beet pulp [16], Fe(III) in limestone [25] and Mn(II) in zeolites [26].…”

The exceedance of nitrate and nitrite concentrations over the water standard quality has caused potential human health dangers such as blue baby syndrome and the growth of aquatic plants (eutrophication). In this work, a Purolite A400 anion exchange resin impregnated by Cu (Purolite A400-Cu) is used to remove nitrate and nitrite in wastewater. High saturation capacities of 0.76 mg N/g and 0.88 mg N/g-nitrate and 0.10 mg N/g and 0.11 mg N/g-nitrite are obtained from Purolite A400 and Purolite A400-Cu. Scanning electron microscope measurement shows that the surface of Purolite A400-Cu is rough due to other deposited materials that originate from Cu deposition. Energy dispersive spectroscopy measurement indicates that the increase in adsorption is due to Cu impregnation with the addition of a positive surface charge on the resin by Cu. The adsorption capacities of nitrate and nitrite decrease with increases in sulphate, phosphate and chloride concentrations. Data are obtained from a fixedbed column using the Thomas equation model. The breakthrough curve shows the C t /C 0 ratio values in Purolite A400 and Purolite A400-Cu. Large C t /C 0 values of 0.55 and 0.52-nitrate and 0.48 and 0.03-nitrite are obtained from Purolite A400 and Purolite A400-Cu.
