ABSTRACT Microfiltration carbon membranes were developed to cope with the ,wastewater, containing ,phenol, and phosphoric ,acid,. The structure of carbon membranes was characterized by scanning electron microscope, x-ray diffraction, bubble pressure method and specific surface area analysis. The separation efficiency of carbon membranes was investigated by varying the operation factors, …

A method for simultaneous quantitative determination of ,phenol, and p -nitrophenol in ,wastewater, was developed by using NIRDRS with a preconcentration procedure of resin adsorption. In the method, the analytes were firstly adsorbed onto the adsorbent, and then the NIRDRS spectrum of the adsorbent was measured for quantitative analysis by partial least squares (PLS) regression.
