Abstract

In order to minimize harmful effect of synthetic dye (direct yellow and direct violet) the capacity of Zn/Al, Zn/Cr and Zn/Fe layered double hydroxides of these contaminant was studied in this work. Batch adsorption experiment was conduct to investigate the effect of various operating parameters such as contact time, initial dye concentration and adsorption temperature in order to provide optimal condition in removal synthetic dye. Based on result, the sorption of direct dye onto LDHs followed pseudo-second-order rate model. The equilibrium adsorption data for both direct dye was fitted Freundlich isotherm model

Abstract

Layered double hydroxides are composed by substitution of metal cation divalent and trivalent. Metal cation divalent and trivalent can be changed. In this work, effect metal cation trivalent (M3+) toward layer formation were studied. Synthesis of LDHs has used co-precipitation methods with molar ratio 3:1 and kept pH at 10. The result of synthesis was characterized by X-ray Diffraction (XRD) and Fourier Transform Infrared (FT-IR) analyses.

Abstract

Thermochemistry as one of sub-subject in chemistry subject which is taught in senior high school. This subject has considered as one of the most difficult subject to be learn by student. In understanding thermochemistry, students often experience misconception because this subject is containing abstract concept and requires representation at the macroscopic, submacroscopic, and symbolic levels. This study was intended to determine the level of student understanding of thermochemical subject after going through the teaching and learning process as an evaluation material for students and teachers. The used research method was descriptive quantitative using a three-tier multiple choice (TTMC) diagnostic test instrument. The subjects of this study were students of class IX IPA 1 Madrasah Aliyah Negri 1 East Lampung in the academic year 2019/2020 with a sample size of 33 students. The obtained results exhibited that student misconception toward the tested subject, including exothermic and endothermic reaction, thermochemistry equation, enthalpy changes, Hess Law, and bonding energy, were 90, 78, 45, 66, and 18%, respectively. The results of the analysis are expected to be an evaluation material for teachers to be able to convey thermochemical material more conceptually to improve student understanding.

Abstract

Layered double hydroxide (LDH) Ni/Al-NO3 was synthesized using a coprecipitation method under base condition following with intercalation using Keggin ion [a-SiW12O40]4- to form Ni/Al-[a-SiW12O40] LDH. The LDHs were characterized using XRD, FTIR, BET, and pHpzc analyses. Furthermore, LDHs were applied as adsorbent of iron(II) from aqueous solution. The adsorption process was studied through the effect of adsorption time, the concentration of iron(II), and temperature adsorption. The results show the interlayer distance of LDHs was increased from 7.408 Ã… to 10.533 Ã… after intercalation process. The adsorption of iron(II) on LDHs showed that adsorption of iron(II) on both LDHs follows pseudo first-order kinetic model with R2 value is close to one. The adsorption process was spontaneous, with adsorption capacity up to 36.496 mg g-1.

Abstract

The prosecutor as an institution conducting the task of prosecution and execution of court decision is expected to uphold its ethics as law enforcement profession. One of the prohibitions for prosecutors is the legal facts that have been regulated in the prosecutor's own regulation as set forth in the code of conduct of the prosecutor. Therefore, the prosecutors must obey the law corridor and obey the law. According to Chaeruddin Ismail, as a whole requires that every law enforcement institution really must have the values of integrity (integrity), fairness, respect for the constitution and governmental authority, honesty, courage ) and compassion so that every law enforcer can be wise and wise in responding to every different situation and condition. The prosecutor has 2 doors of supervision, externally and internally, and a clear procedure in enforcing the code of conduct of the prosecutor itself.

Abstract

Abundant and inexpensive Indonesian natural bentonite was activated by thermal activation at 500 oC for removal of procion red dye as one of the most used synthetic dye in the traditional songket fabric production around Palembang city. Activated bentonite product was characterized by FT-IR, XRD, and thermal analysis. The adsorption process was conducted in batch adsorption system by applying various adsorption parameter condition including, initial pH condition, contact time, and initial dye concentration. The activated bentonite characterization indicates that during the activation process, the structure of the original bentonite was not changed significantly and the result of the thermal analysis revealed that thermal activation at 500 oC was draining the water content without destructing the silica-alumina framework of bentonite. The adsorption kinetics study shows that the procion red adsorption into the activated bentonite follows the pseudo-second order kinetic model. The isotherm adsorption study revealed that procion red adsorption into activated bentonite adapted the Langmuir adsorption isotherm.

Abstract

In this work, two synthetic layered double hydroxides (LDH) consists of Zn2+ as M2+ cation with different M3+ cation, i.e., Al3+ and Cr3+ were used as an adsorbent for Congo Red removal aqueous solution. Both Zn-Al and Zn-Cr LDH were characterized by X-ray diffraction, FT-IR, and BET surface area analyzer. The effect of contact time, initial dye concentration, and temperature were evaluated in a batch technique in order to investigate the characteristic of Congo Red adsorption onto both adsorbents. The experimental data were assessed according to the parameter of adsorption kinetics, isotherm, and thermodynamics. The results of LDH characterization showed that Zn-Al LDH has a higher interlayer distance than Zn-Cr LDH, although Zn-Cr LDH has a higher surface area. The FT-IR analysis indicated the interlayer space of both Zn-Cr and Zn-Al LDH was dominated by CO32- as the interlayer anion species. The adsorption kinetics study of Congo Red on both LDH revealed that the adsorption process followed the pseudo-second-order model. For the adsorption isotherm, the experimental data fit well with the Freundlich model rather than the Langmuir model. The thermodynamic study indicated that the adsorption process that occurred on both adsorbents was spontaneous with exothermic nature.
