摘要

地下水在使用前非常重要的是要注意水质。如果水符合几个参数,包括化学、物理和生物参数,那么它的质量就很好。无机盐含量是测定水质的化学参数之一。本研究采用水热炭化(HTC)法成功地合成了木薯皮的水化产物。该材料是为了减少木薯皮生物质的浪费,克服水的硬度问题而开发的。研究了HTC木薯皮作为硬水软化剂的替代吸附剂。对氢活化(活化型烃)和氢非活化型烃(非活化型烃)的FTIR表征结果包含O-H拉伸、C- h拉伸、C≡C拉伸和C=C拉伸的官能团。用SEM法观察表面形貌上的氢non以大片状形式存在,而表面上的氢activity以小片状形式存在。对Ca2+和Mg2+离子的吸附量分别为85.240 mg/g和87.210 mg/g。同时,对Ca2+和Mg2+离子的非氢吸附容量分别为84,736 mg/g和85,713 mg/g。对Mg2+离子的氢活性吸附动力学发生在3阶(0.000003 min-1),对Ca2+离子的氢活性吸附动力学发生在0阶(0.0324 min-1)。©2021 JNSMR UIN Walisongo。版权所有。

Synthesis of Hydrochar Cassava peels with hydrothermal carbonization method and applications as hard water softener
Groundwater before being used is very important to pay attention to the quality of the water. Water has good quality if it is in accordance with several parameters, including chemical, physical, and biological parameters. Mineral salt content is one of the chemical parameters that can be used to determine the quality of water. In this study, the synthesis of cassava peel hydrochar was successfully carried out using the hydrothermal carbonization (HTC) method. This material was developed to reduce waste of cassava peel biomass and overcome the problem of water hardness. HTC cassava peel was developed as an alternative hard water softener adsorbent. The results of FTIR characterization on hydro-activation (activating hydrochar) and hydro-non (non-activating hydrochar) contain functional groups of O-H stretch, C-H stretch, C≡C stretch and C=C stretch. Observation of surface morphology by SEM method on hydro-non in the form of large sheets, while the surface on hydro-activities in the form of small sheets. The adsorption capacity of hydro-active against Ca2+ ions and Mg2+ ions were 85.240 mg/g and 87.210 mg/g, respectively. Meanwhile, the hydro-non adsorption capacity of Ca2+ and Mg2+ ions were 84,736 mg/g and 85,713 mg/g. The kinetics of hydro-active adsorption on Mg2+ ion took place on order 3 (0.000003 min-1) while when adsorption of Ca2+ ion took place on order 0 (0.0324 min-1).©2021 JNSMR UIN Walisongo.
