Abstract

Rice husk is an organic material that has a high lignocellulosic content so it has the potential to be turned into activated carbon. One method of making activated carbon is activation with a phosphoric acid activator (H3PO4). The purpose of this research was to study the effect of varying concentrations of H3PO4 as an activator on the characteristics of rice husk-activated carbon. The characterization refers to SNI 06-3730-1995 regarding the technical quality requirements of activated charcoal. Activation of rice husk carbon was carried out by contacting the carbon with H3PO4 for 24 hours and shaking it. The H3PO4 consisted of 3 concentration variations, namely 4M, 6M, and 8M. From the research results, the water content was 3.936%; 4.037%; 4.070%, the absorption of iodine has met the character of activated charcoal according to SNI, namely 1217.204 mg/g; 1204.255 mg/g; 1184.832 mg/g while the ash content value does not meet the SNI standard, which is still above 10%. The highest adsorption capacity and adsorption efficiency could be activated with 8M H3PO4, namely 22.42 mg/g and 89.68%. IR spectra on activated carbon with three variations of H3PO4 concentration showed the presence of aromatic C-H, C=C, and C-O anhydride functional groups.
作为活性物质的H3PO4浓度变化对稻壳活体特征的影响
稻壳是一种木质纤维素含量高的有机材料,因此有可能转化为活性炭。一种制备活性炭的方法是用磷酸活化剂(H3PO4)进行活化。本研究的目的是研究不同浓度的H3PO4作为活化剂对稻壳活性炭特性的影响。关于活性炭的技术质量要求,其特征参见SNI 06-3730-1995。稻壳碳的活化是通过与H3PO4接触24小时并摇动进行的。H3PO4由4M、6M和8M三个浓度变化组成。从研究结果来看,含水量为3.936%;4.037%;碘的吸收率为4.070%,符合活性炭的SNI特性,即1217.204mg/g;1204.255毫克/克;1184.832mg/g,灰分值不符合SNI标准,仍在10%以上。8M的H3PO4可以活化最高的吸附容量和吸附效率,分别为22.42mg/g和89.68%。在活性炭上,随着H3PO4浓度的三种变化,红外光谱显示存在芳香族C-H、C=C和C-O酸酐官能团。
