[Heavy Metal Ion Adsorption Properties and Stability of Amine-sulfur Modified Biochar in Aqueous Solution].

A novel biochar was prepared by modification with corn straw, ethylene triamine, and carbon disulfide, and its adsorption properties and stability with respect to heavy metal ions in single and mixed systems (Pb, Ni, and Cd) were investigated. Characterization analysis confirmed the successful modification of an amine-sulfur double group on the surface of the biochar, which had abundant functional groups with a large specific surface area. Adsorption experiments under the single system indicated that the adsorption equilibrium time was 4 h and the optimum dosages were 1, 0.

¹⁸F-fluorodeoxyglucose PET/CT findings of a solitary primary hepatic lymphoma: a case report.

Primary hepatic lymphoma is extremely rare, and only a few cases have been described on positron emission tomography (PET) or PET/computed tomography (PET/CT) imaging in the English literature. We report a case of a 55-year-old woman who presented with low-grade fever and weight loss of three months. On CT scanning, a mass was identified which appeared to be a hypoattenuating lesion, on ultrasonographic imaging, the mass was hypoechoic, therefore, liver abscess or hepatic metastasis from a gastrointestinal primary was initially suspected.
