Walnut shell has been used in various experimental studies for different dyes removal, but it is exciting to study the adsorption behaviour of bio‐waste (walnut shell) in combination with spinel zinc ferrite which resulted in the formation of a novel material having magnetic properties and help in easy separation after the wastewater treatment. Novel magnetic walnut shell zinc ferrite (WSZF) composite has been synthesized and used to remove Malachite Green and Methylene Blue from aqueous solution in single and binary dye systems. Different techniques have been used to characterize the composite such as Fourier Transform Infrared Spectroscopy, X‐Ray Diffraction, Field Emission Scanning Electron Microscopy, Energy Dispersive Spectroscopy, Thermogravimetric Analysis and pHzpc. Adsorption of dyes were studied to see the effect of time, pH, adsorbent dose, dye concentration and temperature. The Lagergren pseudo second order model fitted well among various kinetic models employed. Langmuir adsorption isotherm best fitted with maximum adsorption capacities of 86.20 and 169.5 mg/g in single dye and 23.92 and 18 mg/g respectively in binary dye system for Malachite Green and Methylene Blue. Process was spontaneous and ΔH° were found positive, confirmed endothermic process of adsorption. The composite‘s regeneration capacity was studied for five cycles and at the end of five cycle the efficiency of the material was found to be around 80 % for both single as well as binary dye systems. It is concluded that the chosen WSZF will be the optimum solution for cationic dyes removal.

“…Potentially toxic elements (PTEs) in the soil are enriched through food crops and other means, which has an impact on human health and ecosystems [ 1 , 2 , 3 , 4 , 5 , 6 , 7 ]. Chinese soils are contaminated by PTEs to varying degrees, and the level of PTE contamination in southern China is generally higher than that in the north [ 8 ].…”

Potentially toxic element (PTE) contamination in soils has serious impacts on ecosystems. However, there is no consensus in the field of assessment and monitoring of contaminated sites in China. In this paper, a risk assessment and pollution monitoring method for PTEs was proposed and applied to a mining site containing As, Cd, Sb, Pb, Hg, Ni, Cr, V, Zn, Tl, and Cu. The comprehensive scoring method and analytical hierarchical process were used to screen the priority PTEs for monitoring. The potential ecological risk index method was used to calculate the risk index of monitoring point. The spatial distribution characteristics were determined using semi-variance analysis. The spatial distribution of PTEs was predicted using ordinary kriging (OK) and radial basis function (RBF). The results showed that the spatial distribution of As, Pd, and Cd are mainly influenced by natural factors, while Sb and RI are influenced by both natural and human factors. OK has higher spatial prediction accuracy for Sb and Pb, and RBF has higher prediction accuracy for As, Cd, and RI. The areas with high ecological risk and above are mainly distributed on both sides of the creek and road. The optimized long-term monitoring sites can achieve the monitoring of multiple PTEs.

“…3 Among these methods, adsorption is considered the most promising for As(V) removal as it has the advantages of a simple operation, easy maintenance, low energy consumption, and cost-effectiveness. 8,9 The effectiveness and cost efficiency of the adsorption process largely depends on the properties of the adsorbent material. Recently, biochar obtained from biomass pyrolysis has been extensively studied as a viable adsorbent for water and wastewater treatment.…”

Significant quantities of Fenton sludge (FS) are produced during the treatment of industrial wastewater from the plating industry because of the removal of residual organic matter and color‐causing substances. This study proposes repurposing waste FS as a valuable resource to contribute to environmentally favorable remediation initiatives. This study focuses on producing Fenton sludge biochar (FS‐BC), which effectively removes As(V) from wastewater and offers a sustainable solution for wastewater treatment. Different FS‐BC samples were produced at various pyrolysis temperatures (300–900 °C), with FS‐BC‐900 exhibiting the greatest As(V) adsorption capacity. As(V) removal was primarily mediated by electrostatic attraction with iron oxide, and adsorption via inner‐sphere complex formation, as revealed by the XPS analysis. FS‐BC‐900 had a remarkable maximum As(V) adsorption capacity of 148.7 mg/g (initial concentration: 100–900 mg/l; reaction time: 96 h; pH 7.86), surpassing many other adsorbents reported in the literature. FS‐BC‐900 also demonstrated a high As(V) removal percentage, with 6.67 g/l of FS‐BC‐900 removing 96.8% of the As(V). Notably, the adsorption of As(V) by FS‐BC‐900 was affected by certain factors, including pH and carbonate presence. High pH and carbonate inhibited the ability of FS‐BC‐900 to adsorb As(V). This study presents a novel method for utilizing FS to combat As(V)‐contaminated water‐induced environmental contamination. This study contributes to eco‐friendly and sustainable wastewater treatment and As(V) remediation strategies by transforming waste into valuable resources.
