Abstract

Modifikasi zeolit mangan dengan TiO2 sebagai filter gas buang kendaraan bermotor telah berhasil dibuat dengan mencampurkan zeolit mangan dan TiO2 serta Poly Vinyl Alcohol (PVA) sebagai perekat. Pembuatan filter dilakukan dengan metode reaksi padat-padat (solid State Reaction) kemudian dikarakterisasi struktur dan kristalinitas kristal menggunakan X-Ray Diffraction (XRD) dan morfologi serta komposisi kimia menggunakan Electron Microscopy - Energy Dispersive Spectroscopy (SEM-EDS). Hasil karakterisasi XRD dan SEM-EDS menunjukan bahwa penambahan TiO2 tidak mempengaruhi struktur kristal dari zeolit mangan yang dapat dilihat dari tidak adanya perubahan dspacing yang spesifik dan tidak terjadi pergeseran sudut 2?, namun terjadi penurunan intensitas puncak difraksi yang menandakan adanya penurunan persen massa salah satu komponen zeolit mangan yakni SiO2. Selanjutnya dilakukan pengujian performa filter dalam penurunan kadar gas CO dan HC menggunakan Gas Analyzer dan Spektrofotometer Serapan Atom dalam pengukuran Pb. Hasil pengujian menunjukkan bahwa filter hasil modifikasi zeolit mangan dengan TiO2 dapat menurunkan kadar CO, HC dan Pb, dimana dengan filter tanpa penambahan TiO2 dan dengan penambahan TiO2 10 dan 20%  secara berturut-turut menurunkan kadar CO sebesar 48,29; 58,14; 58,00%;  kadar HC sebesar 27,83 ; 37,97 ; 45,81 % ; dan kadar Pb  sebesar 90,74 ; 92,08 ; 93.48%.

ZEOLIT MANGAN的描述被修改了TiO2和他的应用程序作为机动车的废气过滤器,在CO、HC和Pb的低水平中
用TiO2改装的zeolit作为机动车的废气过滤器已经成功地将mangan、TiO2和Poly乙烯酒精(PVA)混合在一起。过滤器的制作是通过固体反应方法进行的,然后用x射线衍射和形态学以及化学成分对结构和晶体进行分类。XRD和semal - eds的特性表明,TiO2的加入不会影响zeolit mangan的晶体结构,而zeolit的具体着眼点没有变化,也没有角度2的变化?然而,衍射峰值强度下降,标志着锰的一种西欧利特成分的质量下降了1%。接下来,对CO和HC气体浓度下降的过滤器性能进行了测试,使用Pb测量中的原子吸收气体分析仪和光谱仪。测试结果表明,用TiO2修改的zeolit mangan可以降低CO、HC和Pb的水平,而这些过滤器没有增加TiO2,加上TiO2增加量10和20%58.14;58,00%;HC水平为27.83;37.97;45.81 %;Pb级为90.74;92.08;93 48%。关键词:碳氢化合物、一氧化碳、铅、硫、二氧化硅、二氧化硅二氧化硅与硫过滤气体排气管的聚合,已由混合锰、锰和少量乙烯酒精(PVA)成功制造。过滤被固态反应方法掩埋,晶体结构和晶体被x射线分解和化学分解分解的方法埋葬。XRD和semeds的结果表明,TiO2的添加并不影响到锰的晶体结构。侧移,但在质量的峰值强度中有一个衰减峰,这是一个压缩锰的zeolite namely SiO2。Furthermore,一项用Pb测量用的气体分析仪和原子吸收仪进行的过滤性能测试。结果表明,带有TiO2的manganese zeolite的过滤器可以在这些过滤器中减少碳氧的消耗58.14;58 . 00%;23.83;37 . 97;45 . 81%;Pb套餐除以90.74;92。08;93 respectively了48%。氢化合物,碳氢化合物,锰,铅,硫
