An inexpensive and effective adsorbent was developed from bagasse fly ash, obtained from a sugar industry, for the dynamic uptake of lead and chromium. Lead and chromium are sorbed by the developed adsorbent up to 96-98%. The removal of these two metal ions up to 95-96% was achieved by column experiments at a flow rate of 0.5 mlmin(-1). The adsorption was found to be exothermic in nature. The adsorbent was successfully tried for the removal of lead and chromium from wastewater in our laboratory. The developed system for the removal of two ions is very useful, economic, rapid, and reproducible.
一种由制糖工业产生的蔗渣飞灰开发的廉价且有效的吸附剂，用于动态吸附铅和铬。铅和铬被所开发的吸附剂吸附率高达96 - 98%。通过柱实验，在流速为0.5 mlmin(-1)时，这两种金属离子的去除率达到95 - 96%。发现吸附本质上是放热的。在我们实验室，该吸附剂已成功用于去除废水中的铅和铬。所开发的去除两种离子的系统非常有用、经济、快速且可重复。
