Abstract

Deposition of zinc phthalocyanine (ZnPc) layer on top polistiren surface by vacuum evaporation method has been investigated. PS layer was coated on QCM surface by spin coater and ZnPc layer was deposited on its surface by vacuum evaporator with three variation of deposition rate, i.e 1.39 ´ 10-4, 8.08 ´ 10-2 dan 7,41 ´ 10-1 μm/s. The morphology and surface roughness of ZnPc layer was observed by scanning electron microscope (SEM) and non-contact topography measurement system TMS-1200 TopMap. SEM image of ZnPc layer with deposition rate of 1.39 ´ 10-4, 8.08 ´ 10-2 and 7.41 ´ 10-1 μm/s shows porous and fibre like structure. The size of pores and fibre structures of ZnPc layer that produced by deposition rates of 1.39 x10-4 and 8.08 x10-2 μm/s is smaller than size of pores and fibre that produced by 7.41 ´ 10-1 μm/s. Moreover, increasing the deposition rate result a lot of ZnPc molecules make a bonding as fibrous result in the volume of fibrous increasing. Moreover, the increasing fibre size result pores volume increase. Therefore deposition rate can affect surface roughness, and roughness value is proportional to morphology of ZnPc layer. Based on result of TMS-1200 TopMap, the highest roughness level is 1310 nm, it’s found on the ZnPc layer that produced by deposition rate of 7,41 ´ 10-1 μm/s.

Abstract

The thickness measurement of PS thin films on QCM surface and ZnPc layer on QCM/PS using Sauerbrey equation and Scanning Electron Microscope (SEM) has been investigated. Calculation result using a modified Sauerbrey equation show the thickness of PS layer and ZnPc one are 0,45 μm and  0,0676 μm respectively. Additionally the thickness measurement by using SEM shows the thickness of PS  layer is 5,33 μm and the  thickness of ZnPc layer is 10,44 μm. The differences thickness between Sauerbrey equation and SEM topograph is due to layers porosity. The topography of thin films produced by the secondary electron beam scanning allows to get a magnification of SEM image so that it can be measured directly. While the thickness calculation using the Sauerbrey equation is based on the change in the resonance frequency of QCM.

Abstract

Surface modification of QCM by applying polystyrene (Ps) as a coating layer has been investigated. The PS layer was coated onto QCM sensor by using spin coating method. Polystyrene was dissolved in two different solvents i.e., xylene and Tetrahydrofuran (THF) with various concentration i,e 1%, 2%, 3%, 4%, 5% and the velocity angular of spin coater were 1500 rpm, 2000 rpm, 2500 rpm, 3000 rpm, 3500 rpm, dan 4000 rpm. The results show that different solvent result in the difference of thickness of polystyrene coating layer. By calculation with the Sauerbrey equation, the thickness of Ps layer using xylene solvent show 0.1 µm, 0.28 µm, 0.35 µm, 0.59 µm, and 0.81 µm. While by using THF, the thickness of each Ps layer are 0.15 µm, 0.43 µm, 0.84 µm, 0.97 µm, 1.28 µm. On the other hand, by applying different velocity of spin coater, the thickness of polystyrene with xylene are 0.486 µm, 0.445 µm, 0.432 µm, 0.350 µm, 0.320 µm, 0,290 µm, respectively. Moreover, the thickness of PS layer by using THF show 1.05 µm, 0.93 µm, 0.87 µm, 0.84 µm, 0.67 µm, 0.52 µm. Vapor pressure of each solvent is considered as the main property of solvent which influence the thickness of coating. The vapor pressure of THF (143 mmHg) is higher than the vapor pressure of xylene (72 mmHg), the thickness Ps layer with THF is thicker than that of by xylene solvents.

Abstract

A Study on biosorption of gold solution (Au) by Saccharomyces cerevisiae has been caried out. These studies included determination of optimum pH, optimum Au solution concentration,  isotherm and biosorption capacity based on termodinamycs theory, and mechanims of interaction between Au ion and Saccharomyces cerevisiae biosorben. Mechanisms of interaction were known with Au ion on Saccharomyces cerevisiae biosorben using aquadest and 1 M HCl. The result showed that the optimum adsorption process of Au solution by Saccharomyces cerevisiae biosorben took place on pH 5, adsorbat concetration of 100 mg/L was 2.2321 mg/g of yeast. The adsorption isoterm followed the Langmuir adsorption with regresion value of 0.8550 (R2= 0.8550), that indicates that the chemisorption process occurred on the first monolayer on the adsorbent surface. From the thermodynamics theory gives Gibbs free energy of the process a value of ΔG = -0.09195 kJ/mol and showing spontaneous physisorption process. The number of Au ion desorption by using HCL was 73.98%, whereas by using aquades it was 35.42%. It indicated that the main interaction between Saccharomyces cerevisiae biosorben and Au ion was chemisorption.
