“…Then, 0.5 g samples were weighed into a 50 ml conical flask, digested (270 • C) in the mixture of nitric acid and perchloric acid (6:1), and then diluted with deionized water to make a 25 ml solution. The minerals (iron, copper, calcium, phosphorus, manganese, and magnesium) were assayed by inductively coupled plasma emission spectroscopy (Optima 7300 DV, PerkinElmer Co., United States) (Esaka, 2017). Values in the same row (a-e) or in the same column (A-C) with different letters are significantly different (P < 0.05).…”

IntroductionMn, which is an essential trace mineral for all animals, has functions in skeletal system development, carbohydrate and lipid metabolism. The aim of this study was to clarify the effects of different manganese (Mn) sources in basal diets on nutrient apparent digestibility, fecal microbes, and mineral elements excretion before and after weaning.MethodsA total of 15 Holstein heifer calves (6-week-old, 82.71 ± 1.35, mean ± standard error) were randomly designed into three groups (five each): no extra Mn supplemented (CON), 20 mg Mn/kg (dry matter basis) in the form of chelates of lysine and glutamic acid in a mixture of 1:1 (LGM), and 20 mg Mn/kg (dry matter basis) in the form of MnSO4. All calves were weaned at 8 weeks of age. The experiment lasted for 28 days (14 days before weaning and 14 days after weaning). Dry matter intake (DMI) was recorded daily. The animals were weighed by electronic walk-over, and body size indices were collected using tape on days −14, −1, and 14 of weaning. The feces of calves was collected to measure the apparent digestibility of nutrients (acid insoluble ash was an internal marker) and bacterial community on days −1, 1, 3, 7, and 14 of weaning. Fecal mineral concentration was determined by inductively coupled plasma emission spectroscopy on days −1, 1, 7, and 14 of weaning.ResultsThe results showed that, compared with the CON group, adding LGM to diets containing 158.82 mg/kg Mn increased the apparent digestibility (P < 0.05). The Chao 1 and Shannon index of fecal bacteria decreased at day 1 in the LGM and MnSO4 groups and increased after weaning. The PCoA results indicated that the LGM group was distinctly separate from the CON and MnSO4 groups during the whole experimental period. Significant differences (P < 0.05) were observed in the relative abundance of two phyla (Proteobacteria and Spirochaetota) and eight genera (Alloprevotella, Prevotellaceae_UCG-001, Clostridia UCG 014, RF39, UCG-010, Pseudomonas, Ralstonia, and Treponema) in three groups. Moreover, the LGM group showed less excretion of Fe, P, and Mn than the MnSO4 group.DiscussionIn summary, 20 mg Mn/kg diet supplementation improved nutrient digestibility, changed the fecal microbial community, and reduced mineral excretion. Organic Mn supplementation in the diet had more advantages over the sulfate forms in weaning calves.

“…The common method for detecting HM ions is instrumental analysis 9 . The commonly used instrument methods include atomic absorption spectrometry (AAS), 10 atomic fluorescence spectrometry (AFS), 11 inductively coupled plasma mass spectrometry (ICP), 12 X‐ray fluorescence spectrometry (XRF), 13 etc. But the instrumental method requires a high level of professionalism from the technician.…”

Heavy metal (HM) pollution is getting worse with the society progress. Identification and separation of HM ions are urgent issues in environmental protection and social development. In this work, 4‐bromo‐1,8‐naphthalic anhydride was first reacted with amino‐propylene glycol to synthesize naphthimide fluorophores bearing two hydroxyl groups. And then, –Br was substituents by 8‐mercaptoquinoline, 2‐mercaptoimidazole, and 4‐mercaptopyridine, respectively. Eventually, it was reacted with 1,5‐naphthalene diisocyanate (NDI) to synthesize fluorescent polyurethane (PU) films through the reaction between –OH and –NCO. It is found that the PU film not only has a specific identification ability to Hg2+/Hg+ and Fe3+ ions, but also can efficiently remove Hg2+/Hg+ and Fe3+ ions through adsorption. In addition, selective identification by fluorescence quenching was investigated. It is due to the photoinduced electron transfer mechanism (PET). Furthermore, the lowest detection limits for Fe3+, Hg2+, and Hg+ were 6.0 × 10−7 M, 4.7 × 10−7 M, and 9.7 × 10−7 M, respectively, which reflected the sensitivity of the probe and made it fluorescence probes. The three fluorescent small molecules were incorporated into PU, which not only retain their identification function, but also serve the purpose of adsorption and separation of HM ions.

“…12 The addition of NaNO3 revented the leakage of Aliquat 336 from the membrane and the reduction of Cr(VI), caused by the leaking of Aliquat 336 in the sample. Inductive coupled plasma mass spectrometry (ICP-MS) is the most sensitive method for metal determination among atomic spectroscopic methods, 13,14 which are commonly unable to distinguish between Cr(VI) and Cr(III). For MS detection, another problem is interference caused by the overlapping of Cr peaks at m/z = 52 and 53 with molecular ions.…”
