In this study, the degradation of Dicamba methyl ester (DME) was investigated using a low-cost chlorine/ferrous process. The degradation yield was determined by examining the influence of several factors, such as NaClO concentration, dicamba concentration, FeSO4 catalyst mass, and initial solution pH, over a 15 min period. To determine the optimal conditions for DME degradation, an artificial neural network (ANN) model with 4-5-1 architecture was developed. The particle swarm optimization (PSO) algorithm was then utilized in conjunction with the ANN model to identify the optimal factor levels predicted yield of 88%. The following optimal conditions were identified: [NaClO] = 422.3 μM, [Dicamba] = 4.4 mg/L, [FeSO4] = 9.5 mg/L, and a pH of 2.56. GC/MS analysis was conducted to identify the byproducts that were generated during DME degradation. Benzene, 1,2,4-trichloro-3-methoxy DME-BP (m/z 210) was the only identified byproduct that contained chlorine in its structure. A proposed reaction pathway for the DME degradation was suggested based on the obtained mass spectra. In the final stage of the study, total organic carbon (TOC) removal was analyzed using a Fenton-like process under optimized conditions for a duration of 195 min. To confirm the effectiveness of DME and its byproduct degradation, toxicity assessments were performed using the Chlorella vulgaris microalgae as a model organism. The results indicated a low toxicity of 20% when the DME mineralization reached 62.52%. These findings provide strong evidence that support the effectiveness of the proposed low-cost system for DME removal.

The removal of dyes from polluted water has been reported by Dai et al [127], Zhao et al [128], and Ly et al [129]; chlorine contamination in water being removed by Iranian bentonite was reported by Moradi et al [130]. From the chronological data and the trend, it can be deduced that, in all cases, organoclay was predominantly used for the removal of aqueous pollutants.…”

Natural clay mineral and its modifier called modified clay have been used in many environmental applications for a number of years. However, they are not capable enough to achieve a higher conversion rate and so-called ecological sustainability. This can be due to a lack of understanding of the selectivity of the clay and its modifier or a lack of compatibility between clay and pollutants. Recently, the development and implementation of green principles into practice have become an emerging field that brings together green chemistry and engineering practices to achieve a pollutant-free environment (air, water, and soil). This review summarizes the role of clay/modified clay in pollution control and discusses the role of green chemistry in creating global sustainability. In this context, this review sheds light on the complete classification of the clay family to identify its properties and to critically examine the applicability of clay and modified clay for air, water, and soil pollution control over the past decade. This is the unique point of this review, showing how the properties of clay/modified clay can be useful for removing any type of pollutant without focusing on a single type of pollutant or clay. Furthermore, the importance of green materials in clay research, as well as the future area of application, was discussed. Overall, this review places value on multidisciplinary researchers to determine the role of the green pathway in the application of clay and modified clay in achieving environmental sustainability.

The treatment or recovery of waste ink constitutes a significant process for the printing and packaging industries, particularly in the flexographic printing of packaging materials. This poses a substantial challenge in the field of waste management science. The application of waste ink recovery, ensuring a safe environment and human health, along with the recovery and sustainability of Earth's resources, has garnered significant global attention. The present research is solely devoted to creating innovative trends without technological barriers for synthesizing a tri‐copolymer to be applied as an effective sorption system for waste ink. The Polyethyleneimine‐Poly Glycidyl methacrylate‐polyethylene glycol diacrylate tri‐polymer (PEI‐PGMA‐PEGDA tri‐polymer) was synthesized and thoroughly investigated using FTIR, TGA, and DSC to confirm its chemical structure, thermal stability, and the shift in melting point affected by radiation dose, respectively. SEM analysis showed significant morphological differences in PEI‐PGMA‐PEGDA tri‐polymer samples before and after treatment with flexographic printing ink waste, offering effective strategies for adsorbing waste printing inks from organic solvents. These findings contribute to a comprehensive understanding of the investigated materials and their potential applications. Additionally, the kinetic study of the sorption efficiency of flexographic ink by two sets of tri‐copolymers with doses of 20 and 40 kGy indicated that 40 kGy has a more efficient capacity. The highest sorption capacity, approximately 97.6%, was observed for a sample of GMA 15% irradiated by 40 kGy with a sorption amount of 2.5 g L−1. This suggests that the current new treatment strategy can be categorized as highly effective waste ink management and should be advocated for in such domains to ensure a safe environment and preserve Earth's resources. The treatment of printing ink for packaging materials is a crucial step towards achieving green printing technology, which must be supported and advanced through research and industrial application.
