- Abstract
In this paper, primary–secondary amino silica nanoparticle (PSASN) was synthesized, and its dye removal ability from single and binary systems containing printing dyes was investigated. The synthesized PSASN was characterized by means of Fourier transform infrared (FTIR), scanning electron microscopy (SEM), and BET analyses. Acid blue 92 (AB92), Direct Black 22 (DB22), Direct Red 31 (DR31), and Direct Red 80 (DR80) were used. The kinetics and isotherm of dye adsorption were studied. The effects of PSASN dosage, pH, salt, and initial dye concentration on dye removal were evaluated. Adsorption kinetic was found to conform to pseudo-second-order kinetics. The maximum dye adsorption capacity (Q0) of PSASN for AB92, DB22, DR31, and DR80 were 113.636, 37.453, 114.943, and 41.152 mg/g, respectively. It was found that dye adsorption on PSASN followed Langmuir isotherm. The results showed that the PSASN as an adsorbent with dye adsorption capacity might be a suitable alternative to remove dyes from colored printing wastewater.
