Evaluation of cytotoxicity, reactive oxygen species and nitrous oxide of nanochitosan from shrimp shell.

In this study, we concentrated on creating copper-benzene dicarboxylate metal organic frameworks (Cu-BDC MOFs) utilizing scrap copper metal that was obtained from used copper electrical wires. For practical applications, powdered forms of MOFs are typically poorly processed; as a result, Cu-BDC/chitosan/alginic beads were created by cross-linking chitosan, alginic acid, and Cu-BDC MOF. The carbaryl pesticide adsorption from wastewater still challenge due to its low adsorption capacity. Therefore, Copper-BDC/chitosan/alginic beads were compared to chitosan/alginic beads, and the results showed that the latter had a more effective adsorption capacity (225.51 mg g-1) than the former (95.71 mg g-1). Through the use of X-ray diffraction (XRD), Fourier transform infrared (FTIR), scanning electron microscopy-energy-dispersive X-ray spectroscopy (SEM-EDX), and Brunauer-Emmett-Teller (BET), the physical and chemical properties of chitosan/alginic and Cu-BDC/chitosan/alginic beads were examined. It's interesting to note that the Cu-BDC/chitosan/alginic beads' morphology is homogeneous and has sizable holes. The uniqueness of the produced materials lends itself to desirable characteristics for the targeted isolation of carbaryl from wastewater. As a result of the current work, MOFs materials for the selective removal of pesticides from wastewater will commercially available and easily process.

Hydrogen sulfide removal from normal heptane using zinc oxide, silicon dioxide and zeolite 13X: adsorption capacity, kinetics, selectivity, breakthrough and regeneration

The search for a solution to the challenge of providing the agriculture industry with complete feeds is relevant to modern animal husbandry in many countries, and protein is a key limiting component in feed. Along with the growth of food production, the waste it produces, which is also a valuable resource of useful components, can be recycled and used. Thus, in slaughter, butchering and meat production, a large amount of waste is generated, including by-products that can be processed further. The extrusion process is one of the best processing methods to improve the nutritional value of ingredients and feed and improve feed efficiency. In modern feed milling operations, extrusion must be considered as the main process for increasing feed profitability. The benefits of the extrusion process in improving the nutritional value and efficiency of ingredients and feeds depend on many factors, such as the structure and chemical composition of the ingredients, the processing conditions and the equipment used in processing. This article substantiates the need to develop technologies for involving production waste in their further use in medium- and long-term growth in the demand for food. A technology for producing an extruded feed additive based on vegetable feed with the addition of slaughter waste is presented. The formulation of a feed additive in which different percentages of slaughter waste of 5.10% and 15% corn was replaced with by-products was studied. The water activity of the obtained extruded feed additives was studied, where, at a content of 15% slaughter waste, it was low compared with that of the other two samples. Further research will allow procuring fodder products with a high biological value and utilising unclaimed by-products of livestock slaughter.
