Background and purpose: Dyes from textile industry are amongst the major pollutants of the environment that are harmful for both human health and the environment. Azo dyes constitute the largest and the most important class of commercial dyes, accounting for 50% of all commercial dyes. This study investigated the efficacy of Cr-doped ZnO nanoparticles in removal of reactive black 5 (RB5) dye fr...

Chitosan/feldspar biobased beads were synthesized, characterized, and tested for the removal of Acid Black 1 dye from aquatic phases. A four-factor central composite design (CCD) accompanied by response surface modeling (RSM) and optimization was used to optimize the dye adsorption by the adsorbent (chitosan/feldspar composite) in 31 different batch experiments. Independent variables of tempera...

A novel approach for the identification and dating of the fountain pen ink entries on paper has been established by ion-pairing high-performance liquid chromatography (IP-HPLC). Twelve black and six red fountain inks have been collected, and their ink entries have been prepared by drawing lines on paper. The chromatographic conditions for separation of their dye components after extraction with...

This study investigates the adsorption behavior of Reactive Black 5 (RB) and Reactive Yellow 176 (RY) from aqueous solution on coal fly ash (FA-CO), HCl-treated coal fly ash (TFA-HCl), and biomass fly ash (FA-BM). In preliminary study, the FA-BM showed the greatest dye adsorption capacity of both dyes, compared to FA-CO and TFA-HCl. Hence only for the FA-BM, the effects of various experiment pa...

Ruthenium N719 is a well-known material used as the dye in commercial dye-sensitized solar cell (DSSC) devices. However, it poses risks to human health and environment over time. On other hand, titanium dioxide (TiO2) has low electron mobility high recombination losses when photoanode this photovoltaic technology device. In addition, using harms health. As an alternative sensitizer compensate o...
