Adsorptive decontamination of doxycycline hydrochloride via Prosopis juliflora activated carbon: Parameter optimization and disposal study.

This study deals with the removal of doxycycline hydrochloride (DOX) antibiotic, from aqueous environment by using Prosopis juliflora activated carbon (PJAC). PJAC was synthesized by chemical activation and pyrolysis of Prosopis juliflora. It was characterized by employing Fourier transform infrared spectroscopy (FTIR), scanning electron microscope-energy dispersive X-ray analysis (SEM-EDX), X-ray diffraction analysis (XRD), and Brunauer-Emmett-Teller (BET) techniques.

Removal of doxycycline hydrochloride from aqueous solution by rice husk ash using response surface methodology and disposability study.

The huge demand and consumption of DOX, its incomplete metabolism, and complex behavior in atmosphere are causing a great ecological issue, which needs to be solved. In the present study, the suitability of rice husk ash (RHA) for the greater sorption efficiency of DOX antibiotic was investigated. Furthermore, disposability study of exhausted RHA was performed using solidification technique and leachate had undergone toxicity test to evaluate the DOX encapsulation ability.

Effect of bacteria on strength properties and toxicity of incinerated biomedical waste ash concrete.

A large amount of biomedical waste is generated worldwide, and this waste is hazardous and infectious. The ultimate solution for the issue of disposal of such waste is incineration and then landfill. This incinerated waste is called incinerated biomedical waste ash (IBWA).

Ofloxacin adsorptive interaction with rice husk ash: Parametric and exhausted adsorbent disposability study.

The present study investigates the adsorptive interaction of rice husk ash (RHA) with Ofloxacin (OFL) antibiotic. The OFL loaded RHA was studied for its disposability by solidification to find its possible use as a building material. Further, toxicity analysis of leachate from the solidified RHA was also studied for probable leaching of OFL.

Bacterial treatment of alkaline cement kiln dust using Bacillus halodurans strain KG1.

This study was conducted to isolate an acid-producing, alkaliphilic bacterium to reduce the alkalinity of cement industry waste (cement kiln dust). Gram-positive isolate KG1 grew well at pH values of 6-12, temperatures of 28-50°C, and NaCl concentrations of 0-16% and thus was further screened for its potential to reduce the pH of an alkaline medium. Phenotypic characteristics of the KG1 isolate were consistent with those of the genus Bacillus, and the highest level of 16S rRNA gene sequence similarity was found with Bacillus halodurans strain DSM 497 (94.

Identification of the potential of microbial combinations obtained from spent mushroom cultivation substrates for use in textile effluent decolorization.

The study presents variation in microbial population of Agaricus bisporus, Pleurotus sajor-caju and Volvariella volvacea spent substrates (SMS) along with ligninolytic enzymes activity and textile effluent decolorization potential of microorganisms isolated from these. The effect of temperature, pH, carbon sources and immobilizing agents on effluent decolorization using different combinations of these microorganisms has also been studied. SMS of P.

An overview on characterization, utilization and leachate analysis of biomedical waste incinerator ash.

Solid waste management is one of the major global environmental issues, as there is continuous increase in industrial globalization and generation of waste. Solid wastes encompass the heterogeneous mass of throwaways from the urban community as well as the homogeneous accumulations of agricultural, industrial and mineral wastes. Biomedical waste pose a significant impact on health and environment.
