Surface Modified Cobalt Ferrite Nanoparticles with Cationic Surfactant: Synthesis, Multicomponent Dye Removal Modeling and Selectivity Analysis

Herein, magnetic cobalt ferrite nanoparticles (CFNPs) was synthesized and its surface was modified by cationic surfactant (cetyltrimethyl ammonium bromide: CTAB) and its potential to selective removal of dye from multicomponent (ternary) system was investigated. Direct red 31 (DR31), Direct green 6 (DG6) and Direct red 23 (DR23) were used as a model dyes. The characteristics of the synthesi...

Amino Acid Coated Silver Nanoparticles: A Green Catalyst for Methylene Blue Reduction

Highly stable and homogeneously dispersed amino acid coated silver nanoparticles (ANP) of ≈ 10 nm diameter, ranging from 420 to 430 nm are prepared on AgNO3 solution addition to gum of Azadirachta indica solution at 373.15 K. The amino acids were selected based on their polarity. The synthesized nanoparticles were characterized by UV-Vis, FTIR spectroscopy, HR-TEM, XRD, SEM and 1H-NMR. The coat...

Nb2O5 Nanoparticles Synthesis by Chemical Surfactant-Free Methods: ltrasonic Assisted Approach

In this study, spherical Nb2O5 nanoparticles were synthesized by a novel chemical method as a simple, robust, surfactant-free, non-toxic and widely applicable approach. In order to investigate the effect of initial concentration on particle sizes, nanoparticles with different initial concentration were synthesized. Ultrasonic assisted method was applied and the effects of ultrasonic treat...

Parameters Affecting the Biosynthesis of Gold Nanoparticles Using the Aquatic Extract of Scrophularia striata and their Antibacterial Properties

Green synthesis is a simple, low-cost, non-toxic, environmentally friendly and efficient approach touse. Leaf extract of plants rich in polyphenols, such as flavonoids, is a powerful agent in reducing thesynthesis of gold nanoparticles. The purpose of this study is to investigate the parameters affecting thebiosynthesis of gold nanoparticles using the aqueous extract of Scroph...
