六種有機介質對銅的吸附能力

By Shen-Lin Lin, Hsiang-Yi Huang, 黃祥益 and 林深林

Abstract

不同介質對銅的吸附表現及銅的有效性受介質中對有機質、pH值、陽離子交換容量(CEC)等特性的影響,六種供試介質對銅的吸附量均有顯著的差異性,其中以牛糞最高,稻殼最低。在有機介質中添加飽和吸附量的銅溶液,由於銅吸附的狀態不同,使部分介質中的銅在淋洗過程中隨淋洗液流出,並可能在栽培植物過程中釋放成為可夜換性或水溶性狀態,對植物造成傷害。Copper adsorption and availability was found affected by media factors such as oraganic matter, pH and cation exchange capability (CEC). There was significant difference in the adsorption quantity of six tested media. Due to the different stae of copper adsorption, the addition of saturated copper to the organic media may cause plant injury by the release of exchangeable or water soluble copper from the media during the growth period of tomato plants
