Low-cost adsorbents were tested to remove anionic surfactants from laundry rinsing water to allow re-use of water. Adsorbents were selected corresponding to the different surfactant adsorption mechanisms. Equilibrium adsorption studies of linear alkyl benzene sulfonate (LAS) show that ionic interaction results in a high maximum adsorption capacity on positively charged adsorbents of 0.6-1.7 gLA...

The aim of this study was to investigate the efficiency of four different mineral liners (clay, bentonite, kaoline, and zeolite) which could be utilized to prevent the transport of phenolic compounds to groundwater through alternative liner systems. Four laboratory-scale HDPE reactors with 80 cm height and 40 cm inner diameter were operated for a period of 180 days. Results indicated that the t...

In this investigation, the use of phosphotungstic acid (PWA) and phosphomolybdic (PMA) as well Zn2+ containing kaolin bentonite explored for chemical recycling post-consumer poly(ethyleneterephthalate) (PET) wastes have been explored. The clay supported catalysts 5wt% metals heteropolyacids (HPAs) synthesized using wet impregnation method. Nitrogen adsorption desorption studies, SEM–EDX mapping...

The composition of leachates is very variable and rich in toxic compounds, which requires treatment before discharge into the natural environment order to avoid their impact on and/or human health comply with requirements regulatory standards environment. Among parameters indicating pollution by leachates, we have COD, BOD5, conductivity, pH, presence ammonium ions, nitrite, nitrate, chloride, ...
