High concentration of phosphates in the water can lead to eutrophication which leads to uncontrolled growth of algae (algae blooming). It underlies the need for determining the concentration of phosphate in the aquatic environment. However, the concentration of phosphate may change during storage of samples so that an accurate analysis difficult to achieve unless carried out in-situ. DGT (Diffusive Gradient in Thin Films) is an in-situ measurement method developed for measuring phosphate and metal. In this study the use of Fe-Al-Oxide as a binding gel that is expected to bind phosphate with a capacity greater than ferrihydrite. N, N'-methylenebisacrylamide is used as a substitute for commercial DGT Crosslinker as crosslinking for a cheaper price and selective for small molecule. Ferrihydrite-DGT and Fe-Al-Oxide-DGT are tested with a variety of concentrations, pH, and contact time. In both methods DGT found that the pH for phosphate measurements performed at pH 3. Capacity of Fe-Al-Oxide binding gel known to be higher than the ferrihydrite binding gel with result Cferrihydrite-DGT:Cstart is 76% and CFe-Al-Oxide-DGT:Cstart is 82%.DOI :http://dx.doi.org/10.15408/jkv.v0i0.3597

Available Information

Tris-(8-hydroxyquinoline) aluminum III (Alq3) is a stable metal chelate that has received a great deal of attention over the past years due to its use in the fabrication of organic light emitting diodes (OLED).[1,2] Despite all the interest in this remarkable material very little information on its' solid-state properties and packing exists. Nearly all of the available information comes from studies that have been carried out on vacuum deposited thin films.[1]

Good environmental stability, a high degree of processability, and interesting redox properties associated with its chain heteroatom due to this polyaniline (PANI) have been one of the most extensively studied conducting polymers from the last few years. The chemical and electrochemical processes can be used to synthesize PANI. This chapter mainly focused on physiochemical properties of PANI thin films such as conducting properties, optical properties, magnetic properties, electrical and dielectric properties, mechanical properties, crystalline nature, capacitive properties, sensing properties, charge-discharge properties, thermoelectric properties, redox properties, antioxidant properties, anticorrosion properties, etc.

Polyaniline (PANI) has an exclusive representation probably owing to the fact that it has new applications in several fields of nano-technology. It is known for its straightforward synthesis process, high environmental stability and it can be easily doped by different acids. This chapter deals with the synthesis of PANI by several methods in which oxidative polymerization is the simplest and the most highly studied process. The synthesized PANI thin films can be deposited on different substances by a number of chemical and physical-based methods. These PANI thin films have been characterized by different techniques. FTIR and Raman spectroscopy used for structural analysis of synthesized PANI thin films while the crystalline nature determined by X-ray diffraction (XRD). Similarly, SEM, TEM, and AFM have been used for surface analysis of PANI thin films. The thermal and optical characteristics of PANI thin films studied by TGA and optical absorbance spectroscopy, respectively. The cyclic voltammetry (CV) curve gives information about the electrochemical reaction rate and the redox potential of PANI thin films.
