Summary: The study examined the suppression of heavy metal elution from municipal solid waste incineration (MSWI) fly ash using cement or geopolymer solidification. However, it was found that the volume of the solidified body increases with the addition of solidifying agents, necessitating the need for a novel method to suppress heavy metal elution without decreasing disposal capacity. The use of water repellents such as commercially available silane oligomers, alkyl alkoxysilane compounds, and fatty acids was found to effectively suppress heavy metal elution.

Summary: Research has shown that complete resource utilization of municipal solid waste incineration fly ash (MSWI FA) can be achieved through heat treatment with the addition of kaolin. This process can improve the physical properties of ceramsite and separate and recover dioxins, heavy metals, and valuable chloride. Wet separation can effectively separate and purify the dust carried by the flue gas. Ceramsite with a compressive strength of 24.8 MPa was obtained, while dioxin and heavy metal toxicity were below the standard limits. Enrichment of heavy metals by 12 times and the recovery of valuable chloride were achieved through secondary fly ash separation and purification. The developed process shows a high potential for separating multiple valuable elements from ashes.

Summary: A study on gypsum scaling during reverse osmosis desalination process revealed a nonconventional mechanism of antiscalant efficacy, with scaling taking place via heterogeneous nucleation in the bulk retentate phase. The fluorescent-tagged antiscalants were shown to interact with "nanodust" particles, isolating them from calcium and sulfate ions sorption, and reducing the number of gypsum nucleation centers to diminish the overall scaling rate. The scale formation scenario changes from the bulk medium to sediment crystals growth on the membrane surface at the end of desalination process.

Summary: This study investigates calcium carbonate scaling in the reverse osmosis (RO) desalination process. Two novel fluorescent-tagged scale inhibitors, PAA-F1 and HEDP-F, are used to study their behavior and localization during calcite scale formation. The results show that both inhibitors reduce the size of calcite crystals and their distribution is different from previous studies on gypsum. The application of fluorescent-tagged inhibitors provides a unique opportunity to track the localization of scale inhibitor molecules during calcite scale formation.

Summary: This study investigates the inhibition of gypsum scale in electrodialysis cell using fluorescent-tagged antiscalants. It is found that a polyacrylate with a molecular mass of 4000 Da, used at a concentration of 10(-6) mol center dot dm(-3), is more effective than a bisphosphonate in reducing membrane scaling and also modifies the crystal habit of gypsum. The application of antiscalants in electrodialysis for membrane scaling mitigation is shown to be very promising.

Summary: The study examines the effect of polyacrylic antiscalant (PAA-F1) on the deposition of calcium sulfate. It is found that PAA-F1 significantly reduces the amount of deposit and changes the crystal phase, but its molecules are not detected on the deposited crystals. The experiment shows that PAA-F1 does not block calcium sulfate nuclei or crystal surfaces, but reduces the number of nanodust particles as calcium nucleation sites, leading to a decrease in scale formation rate.

Summary: The present study introduces a new and selective analysis method for determining low xanthate concentrations. This study addresses the growing concern over the environmental impact of xanthates and the need for reliable analysis methods. The method utilizes the complex formation between xanthates and various metal ions in aqueous solution, followed by liquid-liquid extraction and high-performance liquid chromatography, to accurately determine xanthates. By using Cu(II) as the complex metal ion, good separation and high measurement sensitivity are achieved. The method has been optimized for sodium isopropyl xanthate and sodium isobutyl xanthate, with detection limits of 24.7 μg/L and 13.3 μg/L, respectively. With a linear calibration range of 0.1-15 mg/L and a total analysis time of 4-5 min, this method offers a fast and sensitive option for selective xanthate determination.

Summary: This study investigates the influence of colloidal solid nanoimpurities in water samples on scale deposition and antiscalant activity. The results demonstrate that artificially implemented iron hydroxo/oxide and silicon dioxide nanodispersions terminate the antiscaling ability of two different antiscalants. The introduction of colloids enhances calcium sulfate deposition by increasing the number of crystallization centers and consuming the antiscalant. The induction time reflects the interaction of the antiscalant with nanoimpurities, rather than the scale-antiscalant interaction.

Summary: Application of antiscalants is a common practice in industrial scale formation worldwide. Modern methods, such as dynamic light scattering and particle counter technique, have provided a better understanding of scale inhibition mechanisms, which has led to increased criticism of classical views on scale inhibition. Antiscalants compete for crystallization templates to reduce the number of potential crystallization centers, thus slowing down scale formation.
