摘要

车床工业每月产生3-5公斤的车床废铁,对环境污染有负面影响。然而,铁车床废料也有潜力作为制造硫酸亚铁和制造氧化亚铁的原料。将车床废铁与25%的硫酸混合,在温度(50℃;60;70)温度和时间(5;10;15)分钟。合成氧化亚铁的过程是将形成的硫酸亚铁晶体与NaOH混合,然后通过SEM分析表征为纳米颗粒。定性试验结果表明,本研究生产出硫酸亚铁。硫酸铁合成的最佳温度和时间为70℃、15 min,产率为7.52%。SEM分析结果表明,3个样品的氧化亚铁的平均粒径为39.1 nm。摘要:工业贝斯(3-5 kg) /布兰(3-5 kg/布兰)阳(3-5 kg/布兰);Namun limbah besi but juga mempunyai potential sebagai bahan baku pembuatan ferro sulfat和pembuatan ferro oksida。sintes铁硫酸盐dilakukan dengan mencampurkan limbah besi但dengan asam硫酸盐25% dengan varasi suhu (50;60;70)cC dan waktu (5;10;15) menit。制备硅铁、硅铁、硅铁、硅铁、硅铁、硅铁、硅铁、硅铁、硅铁、硅铁、硅铁、硅铁、硅铁、硅铁、硅铁、硅铁、硅铁、硅铁。哈西尔邦,孟哈西尔邦,孟哈西尔邦,硫酸铁达乌吉质量。苏湖丹瓦克图特拜克帕达加工sintesro硫酸铁雅图帕达苏湖70℃丹瓦克图15 menmendengan nilai 7,52%。Hasil企鹅分析SEM terhadap ferro - oksida rerata 3个样品,在ukuran 39,1 nm。

Effect of Temperature and Time of Reaction Of FeSO4 Synthesis and Characterization Of Fe2O3 Nanoparticles from Lathe Iron Waste
The lathe industry produces 3-5 kg / month of lathe iron waste which has a negative impact on environmental pollution. However, iron lathe waste also has potential as a raw material for making ferrous sulfate and for making ferrous oxide.The synthesis of ferrous sulfate is carried out by mixing the lathe iron waste with 25% sulfuric acid with a variation of temperature (50; 60; 70) oC and time (5; 10; 15) minutes.The process of ferrous oxide synthesis is carried out by mixing ferrous sulfate crystals that have been formed with NaOH and then characterized into nanoparticles by SEM analysis.The results showed that the study produced ferrous sulfate from qualitative tests.The best temperature and time in the ferro sulfate synthesis process is at 70oC and 15 minutes with a yield of 7.52%.The results of SEM analysis measurements of the average ferrous oxide of 3 samples obtained a size of 39.1 nm Abstrak Industri besi bubut menghasilkan limbah besi bubut sekitar 3-5 kg/bulan yang menimbulkan dampak negatif terhadap pencemaran lingkungan. Namun limbah besi bubut juga mempunyai potensi sebagai bahan baku pembuatan ferro sulfat dan pembuatan ferro oksida. Sintesis ferro sulfat dilakukan dengan mencampurkan limbah besi bubut dengan asam sulfat 25% dengan variasi suhu (50; 60; 70)cC dan waktu (5; 10; 15) menit. Proses sintesis ferro oksida dilakukan dengan mencampurkan kristal ferro sulfat yang telah terbentuk dengan NaOH dan kemudian di karakterisasikan menjadi nanopartikel dengan analisis SEM. Hasil penelitian menunjukkan bahwa penelitian menghasilkan ferro sulfat dari uji kualitatif. Suhu dan waktu terbaik pada proses sintesis ferro sulfat yaitu pada suhu 70oC dan waktu 15 menit dengan nilai rendemen 7,52%. Hasil pengukuran analisis SEM terhadap ferro oksida rerata dari 3 sampel  diperoleh  ukuran 39,1 nm.
