摘　　要：采用橄榄煮液还原硝酸银制备得到不同形貌、尺寸的银纳米片，考察pH、植物质浓度、硝酸银浓度、滴加方式和滴加流速等对制备得到银纳米材料的形貌、尺寸的影响，结果表明，当采用原始pH、植物质浓度5#20g·L-1和硝酸银浓度f172．5mm时，植物质以60mL·h-1。的速度滴加进硝酸银溶液，可以获得边长约为120nm左右，尺寸分布较为均一的多边形银纳米片。Different morphologies and size of silver nanoparticles were synthesized by Canarium album foliar broths. In order to obtain homogeneous morphology and size of silver nanoparticles,several effective factors,such as pH, concentration of foliar broths,silver nitrate,adding ways and speeds of reagents were investigated. And uniform morphology and size silver nanoplates with a length of 120 nm were obtained on condition of 20 g＂ L-~ foliar broths, 2.5 mm silver nitrate and in a way of foliar broths was added into silver nitrate with speed of 60 mL h-l finally.
