“…[21] Cobalt chromate (CoCr 2 O 4 , CCO) is a typical spinel-type oxide, which has been widely used in the field of photocatalysis due to its high structural and chemical stability, special crystal and electronic structure, high charge transfer, and separation efficiency. [22][23][24][25] However, because CCO is difficult to recover and easy to cause secondary pollution in water, its application in the field of photocatalysis is limited. [26,27] Fardood et al [28] tried to couple MgFe 2 O 4 (MFO) with CCO to form MFO@CCO magnetic nanocomposite so that the nanocomposite could be magnetically separated and recovered.…”

A simple solution combustion method is used to synthesize spinel type MgFe2O4 (MFO) and CoCr2O4 (CCO) oxides, which are combined with the mechanical mixing method to construct a Z‐scheme MFO/wt%CCO heterojunction, which effectively degraded tetracycline hydrochloride (TC) under simulated sunlight irradiation. Various characterization techniques are used to confirm the phase structure, composition, near‐spherical morphology, ferromagnetic behavior, optical properties, and photocatalytic activity of Z‐scheme MFO/wt%CCO heterojunction. A variety of environmental experimental parameters confirmed that when the optimal initial TC concentration is 50 mg L−1, the catalyst content is 1 g L−1, and pH 13, the degradation percentage of TC by the MFO/75%CCO composites reached 89%. Active species verification experiments showed that the hole (h+), hydroxyl radical (•OH), and superoxide radical (•O2 −) are the main active species in photocatalytic reactions. Based on mass spectrometry, toxicity analysis, and energy band theory, the degradation pathway, toxicity, and photocatalytic mechanism of MFO/75%CCO composites for the degradation of TC are discussed in detail.

“…Phytoremediation can reduce the level or toxicity of PTEs in the soil environment. Compared to physical (plowing), chemical (soil cleansing), and electrical (electro-extraction) soil remediation methods [ 5 ], phytoremediation is a beneficial remediation technique because it prevents secondary pollution and can be used for massive-scale applications [ 6 , 7 ]. Plants with high biomass and good tolerance to PTEs have been discovered for phytoremediation in recent years [ 8 ].…”

Phytoremediation is an environment-friendly method for toxic elements remediation. The aim of this study was to improve the phytoremediation efficiency of Brassica juncea and the rhizosphere soil micro-ecology in cadmium (Cd) and arsenic (As) contaminated soil. A field experiment was conducted with six treatments, including a control treatment (CK), two treatments with two contents of Trichoderma harzianum (T1: 4.5 g m−2; T2: 9 g m−2), one biochar treatment (B: 750 g m−2), and two combined treatments of T1B and T2B. The results showed Trichoderma harzianum promoted the total chlorophyll and translocation factor of Brassica juncea, while biochar promoted plant biomass compared to CK. T2B treatment showed the best results, which significantly increased Cd accumulation by 187.49–308.92%, and As accumulation by 125.74–221.43%. As a result, the soil’s total Cd content was reduced by 19.04% to 49.64% and total As contents by 38.76% to 53.77%. The combined amendment increased the contents of soil available potassium, phosphorus, nitrogen, and organic matter. Meanwhile, both the activity of glutathione and peroxidase enzymes in plants, together with urease and sucrase enzymes in soil, were increased. Firmicutes (dominant bacterial phylum) and Ascomycota (dominant fungal phylum) showed positive and close correlation with soil nutrients and plant potentially toxic elements contents. This study demonstrated that phytoremediation assisted by biochar and Trichoderma harzianum is an effective method of soil remediation and provides a new strategy for enhancing plant remediation efficiency.
