“…The band at 1610 cm –1 is due to the vibration of CC in the aromatic nucleus. The vibration at 1100 cm –1 is related to the vibration mode of C–O–C. ,− In brief, the FTIR observation confirms that the as-prepared RNC-0 and RNC-2 contains lots of −OH.…”

Methylene blue (MB) is a water-soluble organic compound with a complex chemical structure and stable properties, which is difficult to remove. In this work, a high specific surface area MB dye adsorbent of 3D hierarchical porous derived carbon was obtained from moldy rice noodles (RN) through high-temperature carbonization and strong alkali etching. The morphology and structural properties, pore structure, specific surface area, and crystallinity of RN carbon (RNC) are analyzed. The adsorption properties of RNC for MB dye molecules are studied, including the influence of different activator (KOH) ratios, the influence of initial concentration of dye, and the influence of adsorption kinetics and thermodynamics on the adsorption of dye. The results show that the optimal ratio of RN to activator is 1:2 (RNC-2), and its specific surface area is the highest, reaching 1693.31 m 2 /g. At 298 K, the maximum theoretical adsorption capacity of RNC-2 is 626.25 mg/g, and at 333 K, the maximum theoretical adsorption capacity is 827.34 mg/g. This work shows that the derived carbon material obtained from moldy RN is a kind of adsorbent material with excellent properties and has a great application prospect in purifying industrial wastewater. This work also means that moldy RN can be recycled rather than discarded. In addition, this material can also be used in fields such as energy storage and catalysis in the future.

“…The different absorption peaks were found at 1366 cm −1 , which corresponds to the C–O stretching; at 1625 cm −1 , and at 3426 cm −1 , they were attributed to the H–O–H stretching of H 2 O molecules present within the network of Mg–Al-LDH. 55 The water peak strongly advocates the formation of Mg–Al-LDH, as hydroxides in prepared materials are liable to form strong hydrogen bonds with water molecules. Furthermore, the FTIR spectrum of the Mg–Al-LDH@MISB composite was also examined in a similar range (Fig.…”

“…The accumulation of heavy metals in soil has become a serious problem, particularly in developing countries (Adimalla & Wang, 2018). Heavy metal pollution poses a serious threat to human health because of the high toxicity, environmental mobility, accumulation in the food chain, and lack of biodegradability of heavy metals (Fei et al, 2022; Szymańska‐Pulikowska et al, 2023; Wdowczyk & Szymańska‐Pulikowska, 2022). In addition, heavy metals persist long term in soil environment and can adversely affect soil fauna and flora through soil–microbial interactions and microbial processes (Kumar et al, 2019; Zhao et al, 2022).…”

Metals can accumulate in agricultural soils, presenting a serious threat to human health; therefore, it is important to analyze the quality of these soils to avoid possible harm related to their contamination in the future. Despite the importance of monitoring arable soil quality, few studies have examined the current state of Cu and Cd soil contamination through analysis of historical data and temporal trends in heavy metal content. Therefore, this study was aimed at analyzing the spatial variability of Cu and Cd content (expressed by toxicity indices) and assessing the level of contamination of arable soils in Poland over the last 25 years (1995–2020). The average Cu content in soil throughout the duration of the study was ~10 mg/kg. The average Cd content increased from 0.7 mg/kg (in 1995) to 3.4 mg/kg (in 2020). The evaluation of Cu and Cd soil contamination showed that soils contaminated with Cd and Cu constituted 1.4% and 2.3% of the total monitoring points, respectively. The geoaccumulation index and pollution index ranged for Cu from −5.23 to 3.09 (mean: −2.50) and from 0.02 to 6.40 (mean: 0.20), and for Cd from −5.23 to 6.92 (mean: −1.67) and from 0.01 to 60.58 (mean: 0.44). The soil was practically uncontaminated with Cu and Cd in 98.77%/98.92% and 93.44%/97.92% of cases, respectively. On a national scale, the contents of Cu and Cd in soils depend on soil properties (pH, C, OM, ST, and CM) to a very small extent. An assessment of the spatial distribution of Cu and Cd concentrations in Polish arable soils indicated regional differences related to the degree of industrialization/urbanization. The obtained results show the impact of human activity on the level of heavy metals present in soils.
