We report five cases of button cell ingestion involving infants aged between 9 and 32 months, including four boys and one girl. The ingestion was accidentally discovered in two infants, while in the other three, it was suspected during play. In three cases, mothers attempted to induce vomiting by giving fluids, but the batteries remained in the digestive tract for 38 hours to 5 days. After confirming the diagnosis, the batteries were removed within 4 to 36 hours. The locations of the cells were the esophagus in two cases, the cardia in one, the stomach in one, and the bowel in one. One case involved a large cell in the esophagus, while the others involved smaller cells. Complications occurred in four cases, including esotracheal fistula, esophageal ulceration, and perforation of the jejunum and caecum. In one case, the digestive mucosa appeared normal upon endoscopy. One patient died.展开更多

The AC was characterized by elemental analysis, fourier transform infrared spectroscopy, X-ray diflraction, scanning electron microscopy, thermal gravimetric and diflerential thermal analysis, surface area analyzer and potentiometric titrations. The eflects of initial metal concentration, contact time, pH and adsorbent dose on the adsorption of metal ions were studied. The adsorbent revealed a good adsorption potential for Pb（II） and Cu（II） at pH 6.0 and for Hg（II） at pH 7.0. The experimental kinetic data were a better fit with pseudo second-order equation rather than pseudo first-order equation. The Freundlich isotherm model was found to be more suitable to represent the experimental equilibrium isotherm results for the three metals than the Langmuir model. The adsorption capacities of the AC decreased in the order： Pb（II） Hg（II） Cu（II）.展开更多
