Water pollution is caused by heavy metals, minerals, and dyes. It has become a global environmental problem. There are numerous methods for removing different types of pollutants from wastewater. Adsorption viewed as the most promising financially viable option. Nanostructured materials used effective adsorption techniques to extract metal ions Many nanomaterials, such zero-valent oxides, carbon magnetic nanocomposites, adsorbents. Magnetic nanocomposites adsorbents have properties abundant active functional groups, unique nanomaterials endow them with better than nonmagnetic (classic adsorbents). Nonmagnetic adsorbents) typically limitations limited capacity, adsorbent recovery, poor selective adsorption, secondary treatment. easy recover, strong selectivity high safe economical, always been hotspot research. A large amount data collected in this review, which based on an extensive study synthesis, characterization, capacity elimination wastewater their separation water. The effects several experimental parameters ion removal, including contact duration, temperature, dose, pH, starting concentration, ionic strength, also investigated. In addition, variety illustrations describe various kinetics isotherm models, providing insight into process.

Without the addition of silicon and aluminum sources, a pure-phase KNaLSX zeolite was successfully synthesized from residue (lithium slag), which produced spodumene in production process lithium carbonate. The samples were characterized by an X-ray Diffractometer (XRD), Scanning Electron Microscope (SEM), Fluorescence Spectrometer (XRF), Thermogravimetric Differential Thermal Analysis (TG-DTA), Fourier Transform Infrared (FT-IR), N2 adsorption measurement. ion exchange capacity rate calcium magnesium ions measured as used for detergent builder, results compared with standard zeolites (KNaLSX 4A). experimental show that synthSynthesis characterization co-crystalline composite LSX/esized slag has SiO2/Al2O3 ratio 2.01 grain size 3~4 μm, is close to commercial sample 2.0. BET-specific surface area 715 m2/g, larger than low-silicon X-type (LSX) waste reported literature. constant 5 times 3 4A zeolite, respectively. also high 191 mgMgCO3/g, 2 302 mgCaCO3/g, meets first-grade builders China. work provides basis high-value resource utilization development builder rapid washing.
