摘要
：染料对环境是一个非常严重的问题。由粉煤灰和藻酸钠组成的复合珠粒被证明是一种从染料废料中还原罗丹明b的吸附剂。在本研究中，研究了珠的质量（5-45克）、溶液的pH（2-11）和搅拌时间（0-360分钟）的影响。用紫外-可见分光光度计测定吸附后的浓度。在质量为35克的珠粒的吸附过程300分钟后，获得了31.15%的罗丹明b浓度的最大降低。罗丹明b的吸附对溶液的pH非常敏感，在pH 2时表现出最佳吸附值。基于BET表征，粉煤灰-海藻酸盐珠包括孔径为10 nm、总孔体积为5332 x 10-3 cc/g和孔表面积的中孔。2133平方米/克。
Fly Ash – Alginate Composites Beads for Rhodamine B Removal
: Dyes are a very serious problem for the environment. Composite beads consisting of fly ash and sodium alginate proved to be an adsorbent to reduce rhodamine b from dye waste. In this study, the effect of the mass of beads (5-45 grams), the pH of the solution (2-11) and the stirring time (0-360 min) was studied. Determination of concentration after adsorption was carried out by UV-Vis spectrophotometer. The maximum reduction in rhodamine b concentration of 31.15% was obtained after the adsorption process for 300 minutes with a mass of 35 grams of beads. The adsorption of rhodamine b is quite sensitive to the pH of the solution and shows the optimum adsorption value at pH 2. Based on the characterization with BET, fly ash – alginate beads include mesopores with a pore diameter of 10 nm, a total pore volume of 5,332 x 10 -3 cc/g and a pore surface area. 2,133 m 2 /g.
