ZnO@ activated carbon derived from wood sawdust as adsorbent for removal of methyl red and methyl orange from aqueous solutions

Scientific Reports, Journal Year: 2024, Volume and Issue: 14(1)

Published: March 5, 2024

Abstract Activated carbon (AC) and ZnO@AC composite derived from wood sawdust were prepared to be utilized as adsorbents for methyl red (MR) orange (MO) anionic dyes the aqueous solutions. The maximum adsorption capacity of AC toward both was achieved in strong acidic medium (pH = 3), under stirring 60 min. kinetic studies revealed that MR MO onto fitted well with pseudo-second-order model. Furthermore, intraparticle diffusion Elovich models confirmed is controlled by external surfaces, chemisorption process. isotherm results indicated dye occurred via monolayer adsorption, estimated capacities higher than those AC. Thermodynamic analysis suggested endothermic spontaneous. mechanism MR, proposed electrostatic bonding, π–π interactions, ion exchange, while H-bonding n–π interactions minor contributors. This study reveals potential use carbon-based removal wastewater.

Polluted water containing synthetic dyes from industries of various sectors is a serious hazard to human health as well the rest flora and fauna in environment. It has be treated by efficient yet cost-effective methods such adsorption pollutant dyes. This review summarizes successful one hazardous dye, methylene blue, using polymeric hydrogel nanocomposites adsorbents. These have been proven more active adsorbing than mere parent polymers or pure nanoparticles, seen most cases. effect may contribution high capacities result proposed mechanisms, synergistic enhancement desired characters its components, significance optimum sorption conditions influencing dye onto nanocomposite adsorbent. The porous nature polymer activity nanofillers are potential cause for this research. Not only novel adsorbents remediation pollution but also green approach due spontaneity process without consumption external energy addition being recyclable non-toxic.
