Chemical Modification of Agro-Industrial Waste-Based Bioadsorbents for Enhanced Removal of Zn(II) Ions from Aqueous Solutions

Contamination of water by heavy metals is a major environmental concern due to the potential ecological impact on human health and aquatic ecosystems. In this work, we studied the chemical modification of various fruit peels such as banana (BP), granadilla (GP), and orange ones (OP) in order to obtain novel bio-adsorbents to improve the removal of Zn(II) ions from 50 mg·L−1 synthetic aqueous solutions. For this purpose, sodium hydroxide and calcium acetate were employed to modify the fruit peels. The moisture, extractives, lignin, hemicellulose, and cellulose contents of the raw materials were determined according to ASTM standards. The obtained bio-adsorbents were characterized by scanning electron microscopy (SEM), Fourier Transform Infrared Spectroscopy (FTIR) and thermogravimetric analysis (TGA). The results showed the OP bio-adsorbents performed better, especially when the concentration of the modifier solutions increased, e.g., the OP particles modified using 0.8 M NaOH and Ca(CH3COO)2 solutions resulted in 97% removal of Zn(II) contaminating ions and reached a maximum adsorption capacity of 27.5 mg Zn per gram of bio-adsorbent. The adsorption processes were found to follow a pseudo-second order model. The error function sum of square error indicated the Freundlich isotherm (non-linear regression) as best fit model. The obtained results are particularly interesting for material selection in wastewater treatment technologies based on contaminant adsorption.

“…Certainly, more attention should be directed to speci c residue mixtures that could also generate cryptic, synergistic toxicity effects in bees as well (Xiao et 5 and 6). The comparison of the results with the literature shows that these values remain very high and re ect an intensive use of pesticides, which may present risks, both for human health (Basu et al, 2021), as well as for the environment (Liess et al, 2020). Moreover, the survey results showed that a mixture of different active ingredients (linuron, diquat + paraquat) is the basis of the chemical weed control strategies in potato cultivation.…”

Loukkos perimeter is among the most important irrigated agricultural areas in Morocco. It covers horticulture and market garden production, including potato. This crop is characterized by the intensive use of pesticides that could lead to health and ecological risks, via the food chain and contamination of natural resources, including groundwater. This study aims to assess the use of pesticides in potato cultivation and their impacts on the environment and human health. Here, pesticide use was characterized by the number of treatments (NT), quantity of active substances indicator (QASI) and the treatment frequency indicator (TFI), through eld surveys carried out on 50 Loukkos potato producers. The results showed that farmers use heavy pesticide treatments, mainly against late blight. We determined NT = 19 treatments, total TFI = 28.10 and QASI = 14.86 kg/ha. These values re ect a massive use of pesticides on this crop, which could therefore constitute a challenge and a major constraint for the development of sustainable agriculture in this zone, due to their negative environmental and health effects. It is, therefore, necessary to react quickly to make changes in phytosanitary practices with the aim to monitoring pesticide use via the agro-environmental indicators to reduce health and environmental impact of intensive pesticide use.

“…Tsygankov et al studied the bioaccumulation of OCPs in organisms in the marine environment ( Tsygankov et al, 2019 ). Basu et al investigated bioaccumulation patterns by measuring OCPs in surface water, zooplankton, and some representative fish and shrimp ( Basu et al, 2021 ). Some studies revealed the concentration, spatial distribution, potential sources, and ecological risks of OCPs in the ocean are the focus of academic research ( Khozanah et al, 2022 ; Wang et al, 2022c ).…”
