Activated carbon/titanium dioxide (AC/TiO2) nanohybrids were synthesized by a hydrothermal technique using various weight percent of commercial AC and characterized X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), Fourier transform infrared (FTIR) thermogravimetric analysis (TGA). The applied to photodegradation Reactive Red-35 (RR-35) dye in aqueous solution sunlig...

introduction: the powdered activated carbon treatment (pact) has been proposed as an alternative in wastewater treatment and wastewater biomass protection against toxic substances. this study aims to evaluate pact performance in treating dyes, acid orange, and remazol brilliant reactive blue. methods: this empirical- applied research was carried out in pilot scale in which different dye removal...

Calcium ions have very strong affinity and binds effectively to alizarin red dye during staining of biomaterials. This promotes us to choose calcium hydroxide as a low cost adsorbent for the removal of alizarin red dye. Various parameters such as pH, concentration, dose of adsorbent, time, and temperature have been investigated. In addition, enthalpy, entropy, free energy and activation energy ...
