To address environmental pollution caused by dyes and heavy metals, it is crucial to fabricate effective adsorbent material remove contaminants from the environment. In this research, a biogenic-assisted treatment was applied kaolin clay eliminate arsenic ions (As(V)) malachite green (MG) using an adsorption technique. An environmentally friendly ultrasonic method used incorporate Pterocarpus mildraedii into mesoporous structure of (PMKC) with unique flake-like morphology characterized hexagonal structures formed quartz kaolin. Various analytical techniques were employed analyze functional groups, crystallographic structures, surface properties PMKC. The findings reveal that PMKC, eco-friendly adsorbent, effectively removed As(V) MG wastewater under specific conditions: solution pH 6, PMKC dosage 40 mg/L, contact time 60 min, initial concentration As(V)/MG 100 temperature °C. Furthermore, exhibited high capacities 337.22 mg/g towards 274.73 MG. Dubinin-Radushkevich pseudo-first-order models found best describe experimental data obtained isotherm kinetic studies. Because can be reused remains stable for up ten cycles, holds promise as valuable removing dye metal pollutants.

In this study, a novel biobased treated kaolin clay incorporated with zerovalent nickel (TKC-Ni0NPs) was fabricated and employed as an efficient functionalized adsorbent for the elimination of crystal violet (CV) methyl orange (MO) from textile wastewater. The adsorption capacity TKC-Ni0NPs improved by incorporating functional moieties nanoparticles on structure using experimental data kinetics, isotherm, thermodynamics, reusability study. crystalline structures, groups, morphological characteristics TKC, Ni0NPs, were analyzed X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), high-resolution scanning electron microscopy (HRSEM). point zero charge pH surface evaluated 4.5. adsorptive removal CV MO explored at solution pH, contact time, dosage, initial CV/MO concentration, temperature. Maximum capacities 802.56 812.28 mg/g reported both optimal 6 4 MO, time 60 min, dosage 25 mg/L, concentration 100 temperature 313 K. Remarkably, exhibited favorable behavior in presence cationic anionic coexisting ions. study showed over 92.00 94.00% effectiveness even after 10 cycles, respectively, which holds great promise industrial use. A pseudo-second-order kinetic model effectively suited implying that process is chemisorption controlled. Among isotherm models, Langmuir best fit data. Thermodynamic analysis indicated endothermic spontaneous surface. Consequently, cost-effective, versatile, stable composite significant potential wastewater treatment successfully developed.

Globally produced whey volume is estimated at more than 10 billion tons per year, and only 50 % of the total amount processed turned into products that are safe for environment. In addition, entering wastewater treatment plants leads to disruption facilities' operation further pollution environment, particularly water resources. contrast, main source protein contains other valuable components human organism. Therefore, our target was review recent studies analyse as a component from cheese factories its impact on processes resource processing. Review results indicated need individual highly concentrated streams containing alternative processing methods. The importance avoiding with stream redirecting it identified. Nevertheless, showed has high nutritional value by all indicators: energy (low-calorie product), biological (a wide range irreplaceable substances), physiological (provides comprehensive support most body systems anti-infective action), activity (rich content lactic acid bacteria). Further research possibilities fractional extraction whey's development technologies would allow complex dairy raw materials considered reasonable prospective current needs trends point view.
