Waterless dyeing of polyamide 6.6 using scCO2 (supercritical carbon dioxide) was investigated. PA (polyamide) fibers can be dyed with various dyes, including disperse dyes. The conventional aqueous process uses large amounts water and produces polluted water. Considering these environmental issues, waterless is a forefront issue, utilization supercritical dioxide (scCO2) commercially viable technology for dyeing. This study tested PA6.6 (polyamide 6.6) in at 100 °C 220 bar pressure 45 min. Color measurements color fastness tests were performed, as well tensile strength, scanning electron microscope (SEM) analysis, Fourier transform infrared spectroscopy (FTIR) analysis. fabrics yielded higher K/S (color the Kubelka–Munk equation) values larger molecular weight dye almost same strength medium small-sized demonstrating ability environment without more environmentally friendly option compared to

This study is a review of current knowledge on microplastics (MPs) in aquatic environments. In addition to identifying the sources contamination by MPs water and hazards their presence, an attempt made systematize terminology polymeric microparticles according size describe other parameters characteristic MPs, i.e., shape color. Special focus was placed most important methods used extract from environmental matrices, as well latest effective analytical methods, highlighting advantages disadvantages. The value paper pointing out developments analytics, existing inaccuracies limitations field providing practical guidance. Thanks its comprehensive approach, this article valuable resource for researchers concerned with problem pollution.

The aim of this article is to apply advanced predictive modeling techniques understand the degradation process microplastics in aquatic environments. Utilizing a Fractional Factorial Central Composite Experimental Plan, study seeks develop precise statistical models that enable forecasting quantity pollutants generated during under various environmental conditions. This tool was applied model changes DOC (dissolved organic carbon) and DEHP (bis(2-ethylhexyl) phthalate) values ecosystems. methods were developed using data derived from laboratory tests conducted GC-MS technique. obtained approximating functions, considering factors such as time, water temperature, particle size, significantly reduced analysis time. A two-stage verification functions conducted, accuracy function form, its adequacy, significance input variables, their correlation with DEHP. employed Plan allowed for simultaneous reduction number experiments prediction influence variables on output values. Precise support understanding microplastic process, facilitating development effective strategies managing pollution.
