Green Synthesis of Nano-Zero-Valent Copper for the D-Blue 60 Textile Dye Removal from Aqueous Medium

Abstract

Green synthesis of zero-valent copper nanoparticles successfully performed using Ficus benjamina leaves. The novel adsorbent Ficus nano-zero-valent copper (FB-nZVCu) characterized by utilizing scanning electron microscopy (SEM) and Fourier transforms infrared spectroscopy (FT-IR). The size of these nanoparticles typically ranges from 16 to 18 nm. This adsorbent investigated for removal of D-blue 60 from textile wastewater. The impact of different operating parameters, including pH, adsorbent dose, stirring rate, time, and initial dye concentration, had been tested, and optimum conditions were selected to gauge the optimum dye removal performance of the adsorbent. The maximum removal efficiency of D-blue 60 reached 87% under the following proper conditions: adsorbent dose 0.3 g L−1, time 30 min, and pH 8. The Langmuir isotherm was found to be the most appropriate system for the adsorption process (R2 = 0.9994) and (qmax = 30.03 mg g−1). The pseudo-second-order model defined the adsorption. From the data obtained and the fruitful discussion, it detected that the FB-nZVCu green adsorbent strongly recommended as a hopeful substance for removing D-blue 60 from both synthetic and actual waste samples.Highlights Green synthesis of eco-friendly FB-nZVCu nanoparticles utilizing low-cost material Ficus benjamina leaves. The FB-nZVCu nanoparticles are efficient nano-adsorptive agents for removing D-blue 60 from wastewater under optimum conditions. The Langmuir isotherm and PSO kinetics model provided a good fit to the adsorption data.

Optimization of purity and yield of amorphous bio‐silica nanoparticles synthesized from bamboo leaves

“…The results in Figure 2 are also affirmed by ANOVA in Table 2 where all variables have p ‐values of ≥0.1 (or −1.725 ≤ t ‐values ≤1.725) which implies that the hypothesis null is accepted. [ 40 ] In other words, there is no significant effect from any single variable, quadratic interaction, or two variable interaction. Nevertheless, there is still not enough evidence to conclude that all variables in this experiment have no effect on product purity.…”

“…BBD was chosen because it has the capability to optimize the experimental variables as well as analyze the influences of each variable and their interaction effects. [40][41][42][43][44][45] BBD can also reduce the number of runs conducted compared with central composite design (CCD). [46][47][48][49][50] In addition, extreme conditions are not applied in BBD, so the experiment becomes low cost.…”

“…Zayed et al reported those kinds of structures as huge nano-clusters of semi-spherical particles. [40] Agglomeration and DLA allow the particles to stick together and close the particle pore, consequently reducing the surface area. [62][63][64] Nevertheless, the surface area can be increased if the agglomeration process occurs with a branching part.…”

Studies on the Formation and Composition of Copper(II)-α- and γ-Halo-1-Oxobutanilides Complexes

“…All these complex species have been isolated in the solid state and their compositions are confirmed by chemical analysis and FT-IR spectra. These data are interpreted depending upon the previously published data by Zayed et al [18,19,20,21] and used to prove the proposed structures of studied complexes.…”

Sustainable and Green Synthesis of Iron Nanoparticles Supported on Natural Clays via Palm Waste Extract for Catalytic Oxidation of Crocein Orange G Mono Azoic Dye

“…In this work, a green synthesis of NZVI was performed by a novel, easy, and simple method using an abundant and annually renewable palm waste. The extract was obtained using a coffee maker, which differs from conventional methods such as hot extraction, 52 cold extraction, 53 microwave irradiation, 54 and the use of Soxhlet apparatus, 55 which were later used in NP synthesis. HB-NZVI, which is applied as a catalyst for the degradation of monoazo dye Crocein Orange G (COG) by hydrogen peroxide (H 2 O 2 ) in aqueous solution, was synthesized using the local bentonite from El Hamma-Gabes deposit (HB) as a support.…”
