Natural zeolites (NatZ) are widely available, porous, crystalline aluminosilicate minerals that commonly used as cost-effective adsorbents in water treatment processes. Despite their efficiency removing various heavy metal ions from wastewater, NatZ show relatively low affinity toward Ni2+ and Cr3+ ions. This study aimed to develop composite based on hydroxyapatite using two methods, hydrothermal mechanochemical, adsorption properties for the removal of aqueous solutions were investigated....
In the present study, supercritical solvent impregnation (SSI) has been applied to incorporate thymol into bio-composite polymers as a potential active packaging material. Thymol, natural component with proven antimicrobial activity, was successfully impregnated starch-chitosan (SC) and starch-chitosan-zeolite (SCZ) films using carbon dioxide (scCO2) solvent. Experiments were performed at 35 °C, pressures of 15.5 30 MPa, an time in range 4–24 h. The highest yields SC starch chitosan mass...
Abstract Chitosan/gelatin and chitosan/gelatin/zeolite films prepared by solvent casting method are impregnated with a mixture of thymol carvacrol using green solvent, supercritical carbon dioxide at 35 °C 30 MPa, during 18 h. Proposed enables preparation biocompatible biodegradable blends strong antioxidant antibacterial activity, whereby amounts loaded thymol/carvacrol (TC) in the range from 3.3% to 6%. After initial burst release, both types exhibit gradual release bioactive compounds,...
The adsorption of the antibiotic ciprofloxacin (CIP) from an aqueous solution by natural zeolite, calcium-rich clinoptilolite (CLI), and magnetite-coated CLI (MAG-CLI) was investigated. Both MAG-CLI showed a high affinity towards CIP at 283, 288 293 K pH 5. Adsorption kinetics studied for initial concentrations 15–75 mg dm−3 follow Lagergren’s pseudo-second order equation is best represented Langmuir model. mechanism involves strong electrostatic interactions between negatively charged...
Abstract Hospital wastewaters can become a route for dissemination of antibiotic-resistant bacteria to the environment if not properly treated. Some these are able survive conventional disinfection treatments (e.g. chlorination, UV irradiation), which evokes need novel methods. The metal-exchanged zeolites were tested as antibacterial agents wastewater treatment. natural zeolite clinoptilolite enriched with silver (AgNZ) showed far better activity towards hospital pathogenic bacterium...
Low-cost and easily available natural zeolite is a promising adsorbent for metal ions removal in wastewater treatment. The possibility of using zeolitic tuff from Serbia the form Na-enriched (Na-Z) adsorption Pb2+, Zn2+, Cu2+, Ni2+ was investigated presented paper. research included Na-Z characterization determination kinetics individual ion tests non-linear pseudo-first-order (PFO), pseudo-second-order (PSO) mixed-order (MO) kinetic models. results indicate that processes on are complex...
In this study, porous ceramics, based on available and cost-effective raw materials natural zeolite kaolin clay, were synthesized examined as an adsorbent for removing ammonium (NH4+) ions from aqueous solutions. The synthesis was carried out using the foaming method with addition of sodium dodecyl sulfate agent, polyvinyl alcohol organic binder, hydrogen peroxide blowing agent. obtained green sintered samples characterized by thermogravimetric analysis, scanning electron microscopy, X-Ray...
Copper flotation tailings (FTs), resulting from the separation and beneficiation processes of ores, are a significant source environmental pollution (acid mine drainage, toxic elements leaching, dust generation). The most common disposal method for this industrial waste is dumping. However, due to their favorable physical chemical properties—the high content aluminosilicate minerals (60–90%)—flotation can be effectively treated reused through geopolymerization technology, thereby adding...
Due to the development of resistance antimicrobial agents, bacterium Acinetobacter baumannii is nowadays a leading cause nosocomial outbreaks. Clinically relevant A. outside hospital settings including natural soils affected by human waste represents public-health risk for humans and animals. The aim this study was investigate potential metal-loaded zeolites eliminate viable from artificially contaminated soils. isolate subjected activity zeolitised tuff (NZ) Cu-modified (CuNZ) or...
Antibacterial activity of a natural zeolite, clinoptilolite (Z), enriched with about 0.4-0.5 mmol Ag (Ag-Z), Cu (Cu-Z) or Zn (Zn-Z) was tested toward two strains Gram-negative bacteria -Escherichia coli and Acinetobacter baumannii -in seawater from Adriatic Sea (Croatia).The Ag-Z Cu-Z exhibited bactericidal E. A. after 3 6 h exposure, respectively.The Zn-Z showed antibacterial both strains, but lacking the effect even 24 exposure.All studied samples released metal cations in...
