The adsorption mechanism of the removal lead from water by using carboxylic functional group (COOH) functionalized on surface carbon nanotubes was investigated. Four independent variables including pH, CNTs dosage, contact time, and agitation speed were carried out to determine influence these parameters capacity water. morphology synthesized multiwall (MWCNTs) characterized field emission scanning electron microscopy (FESEM) transmission (TEM) in order measure diameter length CNTs....
The carbon dioxide (CO2) capture and utilization strategy has emerged as an innovative multifaceted approach to counteract emissions. In this study, a highly porous muffin polyhedral barium (Ba) ̵ organic framework (BaTATB; H3TATB = 4,4',4″-s-triazine-2,4,6-triyl-tribenzoic acid) was synthesized solvothermally. three-dimensional honeycomb pore architectures were densely populated with Lewis acidic Ba(II) metal sites basic nitrogen-rich triazines. BaTATB demonstrated selective CO2 adsorption...
This study was carried out to evaluate the environmental application of modified and nonmodified carbon nanotubes through experiment removal chromium trivalent (III) from water. The aim find optimal condition water under different treatment conditions pH, adsorbent dosage, contact time agitation speed. Multi wall (MW‐CNTs) were characterized by field emission scanning electron microscopy (FE‐SEM) transmission (TEM). diameter produced varied 20–40 nm with average 24 10 micrometer in length....
In the realm of renewable energy technologies, development efficient and durable electrocatalysts is paramount, especially for applications like electrochemical water splitting. This research focuses on synthesizing a novel bimetallic metal-organic framework (BMMOF11) using earth-abundant elements, cobalt (Co) cadmium (Cd). BMMOF11 showcases distinctive structure with distorted octahedral chains CoO CdO, linked by benzene tricarboxylic acid (BTC). Our study primarily investigates...
