Summary: The presence of nanoparticles in drinking water raises concerns about their potential risks to human health and the efficacy of water treatment plants in removing them. This study examines the efficiency of granular activated carbon (GAC) in removing CeO2 nanoparticles. The results show that GAC has a good affinity for nanoparticles, with higher adsorption capacity and removal efficiency in lake water compared to ultrapure water. The adsorption mechanism is mainly controlled by electrostatic attractions, and mass transfer processes play a role in the removal of nanoparticles in lake water.

Summary: This study proposes the development of a low-cost, renewable, and porous adsorbent derived from Ficus benjamina leaves for removing cationic dyes from wastewater. The adsorbent was characterized and found to have small pore size, high volume, and large surface area. The optimal pH for adsorption varied for different dyes, and the adsorption mechanism was determined to be a two-body interaction. The pulverized dry leaves of Ficus benjamina showed great potential as a batch adsorbent for cationic dyes in wastewater.

Summary: This study investigates the effectiveness of organoclay, derived from the modification of raw clay with Cetyltrimethylammonium Bromide (CTAB) surfactant, as an adsorbent to remove anionic dye methyl orange (MO) from synthetic aqueous solutions. Physicochemical properties of raw clay and modified clay are characterized using FTIR, XRD, and SEM-EDX. Response surface methodology (RSM) based on Box Benhken design is employed to evaluate the interaction between three independent variables (pollutant concentration, adsorbent mass, and dye solution pH). Results show that the removal efficiency of MO is dependent on pH and dose of the composite, with maximum adsorption (99%) achieved under optimal conditions of 0.5 g adsorbent dose, 60 min reaction time, and pH 6. The Langmuir isotherm model accurately describes the adsorption process, with a maximum uptake of 15.58 mg/g. The adsorption kinetics follow the pseudo-second order model. The composite can be reused for 5 cycles without significant loss of adsorbent activity.

Summary: Selective/simultaneous adsorption of Congo Red (CR) and Methylene Blue (MB) has been effectively achieved using amorphous perlite. Optimum conditions of 38 min contact time, 96 mg/L dye concentration, and 312 degrees K temperature resulted in high adsorption yields of 82.22% for CR and 96.65% for MB. The adsorption process was found to occur through intradiffusional mass transport onto the porous material. Thermodynamic parameters indicated an endothermic/spontaneous physisorption process. SEM-EDS characterization revealed the surface adsorption process, while FTIR analysis showed disruption of compound order and decreased crystallinity of the adsorbent after adsorption. Application of these conditions to real industrial wastewater demonstrated simultaneous adsorption at neutral pH and 312 degrees K, with selective adsorption of CR at pH 4 and MB at pH 9.

The addition of 10% calcined kaolinic clay was found to improve the physicomechanical properties of the synthesized geopolymers and result in interesting physico-chemical characteristics at 28 days of age. Incorporating more than 10% calcined kaolinic clay led to the appearance of zeolites in the geopolymer matrix, creating a heterogeneous microstructure and decreasing the mechanical properties of the geopolymers.

The Lehotka pod Brehmi and Jastraba represent economically valuable deposits, with peraluminous, calc-alkaline perlites containing low phenocryst content and silica-rich glass. The formation of perlite from volcanic glass is attributed to hydration by heated meteoric fluids and sustained elevated temperatures, resulting in perlites with low expansion and good mechanical stability.
