OBJECTIVE To study the preparation of seeding type immobilized microorganisms and their degradation characteristics on di-n-butyl phthalate (DBP). METHODS Diatomite, clinoptilolite, silk zeolite, and coal fly ash were chosen as reserved materials and modified. Their adsorption capacity and intensity in the bacteria were determined and the best carrier was picked out. The seeding type immobili...

Abstract Pozzolanic additives set off a fundamental part of high strength and most durable concrete mix design. materials include natural products such as volcanic product (ashes pumice) by-product includes metakaolin, rice husk ash, silica fume, fly ash etc. Diatoms have been utilized one the pozzolanic in industrial sectors construction industries to improve rheological mechanical properties ...

Pt nanoparticles and a CeMnOx composite were loaded on the surface of natural diatomite material to generate Pt/CeMnOx/diatomite using redox precipitation impregnation methods. The physicochemical properties catalysts characterized by means various techniques. catalytic resistance H2O SO2 measured for oxidation typical volatile organic compounds (i.e., toluene ethyl acetate). Among all as-prepa...

The paper studies various modifications of diatomite, aiming at creating sorbents for wastewater purification from heavy metal ions. Diatomite the Akhmatovskoe deposit Penza region was considered as a raw material. processes physical and chemical modification diatomite were investigated. Adsorption isotherms constructed, quantitative characteristics adsorption copper ions on surface modified ob...

B-cell lymphoma is associated with incomplete response to treatment, and the development of effective strategies targeting this disease remains challenging. A new personalized B-cell lymphoma therapy, based on a site-specific receptor-mediated drug delivery system, was developed in this study. Specifically, natural silica-based nanoparticles (diatomite) were modified to actively target the anti...

The clarification of biological feed stocks during the production of biopharmaceutical proteins is challenging when large quantities of particles must be removed, e.g., when processing crude plant extracts. Single-use depth filters are often preferred for clarification because they are simple to integrate and have a good safety profile. However, the combination of filter layers must be optimize...

Diatomite, a porous non-metal mineral, was used as support to prepare TiO2/diatomite composites by a modified sol-gel method. The as-prepared composites were calcined at temperatures ranging from 450 to 950 °C. The characterization tests included X-ray powder diffraction (XRD), scanning electron microscopy (SEM) with an energy-dispersive X-ray spectrometer (EDS), high-resolution transmission el...
