Kelapa merupakan tanaman yang mulai dari akar sampai buahnya dapat di manfaatkan, salah satu bagian buah kelapa jarang manfaatkan bahkan slalu menjadi limbah yaitu tempurung kelapa. Limbah dimanfaatkan sebagai pengganti bahan bakar terbaru dijadikan arang dalam pembuatan briket dengan campuran perekat dan kimia oksidator KMnO4. Penelitian dilakukan bertujuan untuk mengetahui pengaruh presentase...

Background and Purpose: Phenol and derivatives are common pollutants of drinking water which are blamed for crucial adverse effects such as poisoning, cancer, and malformation. In this study, an activated carbon of Miswak’s root (MR) was used for the removal of phenol from aqueous solutions as a low-cost and high surface adsorbent. Materials and Methods: Adsorption exper...

4-Allyl-4-hydroperoxy-2-methoxycyclohexa-2,5-dienone (5) was synthesized by photooxygenation of commercially available Eugenol in the presence of tetraphenylporphyrin (TPP) as a singlet oxygen sensitizer. The brief and one-pot syntheses of some natural product skeletons were conducted using the corresponding allylic hydroperoxide at different temperatures (0 o C and room temperature) with potas...

A method is described for measuring doxepin-related material excreted in urine. Unchanged doxepin and certain doxepin metabolites are oxidized to doxepin ketone with KMnO4. The doxepin ketone is extracted with n-hexane and quantitated by ultraviolet spectrophotometry at the absorption maximum, 266 nm. This method is fast, reproducible, and measures a greater percentage of doxepin-related materi...

Efektivitas Biji Kelor pada Proses Koagulasi Untuk Penurunan Kekeruhan, Logam (Fe), dan Zat Organik (KMnO4) Pada Air. Penelitian ini bertujuan untuk mengetahui efektivitas biji kelor (Moringa oleifera) yang digunakan sebagai koagulan penjernihan air. Penjernihan air dilakukan menggunakan sungai tidak memenuhi standar kualitas bersih parameter kekeruhan, kandungan logam zat organik (KMnO4). Baha...

Lithium-rich NMC (LR-NMC) compounds exhibit high capacities beyond the traditional redox, but it remains unclear whether anomalous charge compensation mechanism is due to oxidized lattice oxygen or migration-assisted Mn oxidation. We compare LR-NMC with a model Mn7+ system (KMnO4) using combination of resonant inelastic X-ray scattering (RIXS) irradiation studies and operando absorption spectro...

In Nigeria, potassium permanganate (KMnO4) is used as a chemical oxidant in the removal of hydrocarbons from polluted soils and groundwater, but there no information on effects KMnO4 geotechnical properties soil. this study, was added separately to lateritic soil kaolin at concentrations 0 %, 2 5% 10 % by weight dry Each mixes then subjected grain size analysis, Atterberg limits, specific gravi...

Title of Thesis: EVALUATION OF LABILE SOIL CARBON TEST FOR PREDICTION OF SOIL PRODUCTIVITY RESPONSE TO ORGANIC MATTER MANAGEMENT Shawn T. Lucas, Master of Science, 2004 Thesis Directed by: Professor Ray R. Weil Department of Natural Resource Sciences and Landscape Architecture A KMnO4 oxidation method for estimating labile soil C (CL) was evaluated for use in a soil testing mode to identify soi...

Titanium dioxide (TiO2) incorporated ordered 2D hexagonal mesoporous silica (SiO2) films on a glass substrate were fabricated for use as a catalytic nanoreactor. Films were prepared using a tetraethyl orthosilicate (TEOS) derived SiO2 sol and a commercially available dispersion of TiO2 nanoparticles (NPs) in the presence of pluronic P123 as the structure directing agent. The effect of TiO2 dopi...
