“…In addition, ΔTOC increased when the Cd(II)/ligand molar ratio changed from 1:0.5 to 1:1. These adsorbed anionic ligand species increased the carboxylic acid groups on the surface of the adsorbent, thereby causing an increment in the adsorption of Cd(II) [34]. This result was consistent with the XPS characteristic of the AMBP after adsorption (Figure 7, a new carboxylic acid group appeared).…”

A new amine group functionalized moso bamboo powder adsorbent (AMBP) was prepared using a facile procedure to remove Cd(II) complexes with citric acid (CA) and tartrate acid (TA). The properties of the AMBP were characterized using SEM, FTIR, XPS, BET, and an elemental analysis. The adsorptive performances of the AMBP toward Cd(II)-CA/TA were investigated. The results indicated that amine group was successfully introduced, and the AMBP with a BET specific surface area of 0.463 m2/g was effective in adsorbing Cd(II)-CA/TA under pH 4.0–10.0. The removal of Cd(II) increased significantly when the Cd(II)/ligand molar ratio changed from 1:0.5 to 1:2. The adsorption processes of Cd(II)-CA/TA were endothermic and fit well with the pseudo-second-order kinetic model (R2 > 0.999). The Langmuir model (qmax of 14.41 and 7.58 mg/g for Cd(II)-CA and Cd(II)-TA, respectively) fit the isotherms better than the Freundlich model. The AMBP could be regenerated by HCl and reused at least 4 times. The uptake mechanisms of Cd(II)-CA/TA were proposed to be physisorption and the chemisorption of the coordination between –NH2/–NH and the Cd(II). This work shows that the AMBP is an adsorbent with high practical value to remove Cd(II) in water or wastewater containing CA/TA.

“…However, plant biomass was decreased with the addition of high concentrations of TA and MA. Based on previous results, CA, TA, and MA around roots can promote plant growth by providing available ion compounds and depolymerizing high-molecularweight humus(Chen et al, 2020c). Also, CA can promote soil phosphorus solubilization, supply more carbon and phosphorus to plant roots, and improve N 2 xation(Wang et al, 2019).…”

Enhancing the uptake and enrichment of heavy metals in plants is one of the important means to strengthen phytoremediation. In the present study, citric acid (CA), tartaric acid (TA), and malic acid (MA) were applied to enhance phytoremediation by Bidens Pilosa L. in Cd-contaminated soil. The results showed that by the addition of appropriate concentrations of CA, TA, and MA, the values of the bioaccumulation factor increased by 77.98%, 78.33%, and 64.49%, respectively, the transport factor values increased by 16.45%, 12.61%, and 5.73%, respectively, and the values of the phytoextraction rates increased by 169.21%, 71.28%, and 63.11%, respectively. The minimum fluorescence values of leaves decreased by 31.62%, 0.28%, and 17.95%, while the potential efficiency of the PSII values of leaves increased 117.87%, 2.25%, and 13.18%, respectively, when CA, TA, and MA with suitable concentration were added. Redundancy analysis showed that CA and MA in plants were significantly positively correlated with plant growth, photosynthesis, and other indicators, whereas TA showed a negative correlation with most indicators. Moreover, CA addition could significantly increase the abundances of Azotobacter, Pseudomonas, and other growth-promoting bacteria, and the abundance values of Actinophytocola and Ensifer were improved in TA treatments. Therefore, our results demonstrated that low-molecular-weight organic acids could enhance phytoremediation, and exogenous CA could significantly improve the phytoremediation of Cd-contaminated soil by Bidens Pilosa L.

“…Higher TA levels were found in the root exudates of Sedum alfredii (Cd hyperaccumulator) signifying its role in phytoextraction (Li et al, 2007;Tao et al, 2019). Follow-up studies revealed a signi cant metal desorption ability of TA contributing to Pb-phytoextraction Chen et al (2020). As a step further, TA soil spiking enhanced Pb root-to-shoot translocation thereby improving Pb-phytoextraction e ciency in turnip (Khan et al, 2022).…”

Phytoextraction of Pb is a challenging task due to its extremely low mobility within soil and plant systems. In this study, we tested the influence of some novel chelating agents for Pb-phytoextraction using sunflowers. The Pb was applied at control (0.0278 mM) and 4.826 mM Pb as Pb(NO3)2 through soil-spiking. After 10 days of Pb addition, four different organic ligands (aspartic, ascorbic, tartaric, and pantothenic acids) were added to the soil at 1 mM concentration respectively. In the absence of any chelate, sunflower plants grown at 4.826 mM Pb level accumulated Pb concentrations up to 104 µg g-1 DW in roots whereas, 64 µg g-1 DW in shoot. By contrast, tartaric acid promoted significant Pb accumulation in root (191 µg g-1 DW; +45.5%) and shoot (131.6 µg g-1 DW; +51.3%). Pantothenic acid also resulted in significant Pb-uptake in sunflower shoots (123 µg g-1 DW; +47.9%) and in roots (177.3 µg g-1 DW; +41.3%). The least effective amongst the chelates tested was ascorbic acid but it still contributed to +39.0 and 45.2% more Pb accumulation in sunflower root and shoots. In addition, plant growth, biochemical, and ionomic parameters were positively regulated by organic chelates. Especially, an increase in the leaf Ca, P, and S was evident in Pb-stressed plants in response to chelates. These results highlight that the use of biocompatible organic chelates positively alters plant physio-biochemical traits contributing to higher Pb-sequestration in sunflower plant parts.
