The aim of the present study was to perform morphological and chemical characterizations microplastics (MPs) found in seawater samples from coast city Fortaleza (CE) using Fourier-transform infrared (FTIR) spectroscopy, Raman spectroscopy differential scanning calorimetry (DSC). Sampling performed a neuston sampler. MPs were separated based on difference density. with varied morphologies found....

The low-cost feedstocks such as sesame (sesamum indicum) and jatropha (jatropha curcas) seed oils were utilized to optimize the yield of alkyd resins. experimentally selected input factors ranges in molar ratios oil:glycerol (0.3 – 1), phythalic anhydride: glycerol (1 3), catalyst (0.5–1.5 wt. %) for optimization established using response surface methodology (RSM) Box Behken model improve resi...

The waste of cooking oil was increased due to the consumption increases. Waste can reuse for raw material after adsorption process with Bayah's natural zeolite, such as feedstock alkyd resins. This paper studied effect mass Bayah zeolite (w/w %) on characteristics oil. Zeolite adsorbent reduce value free fatty acids and peroxide numbers first stage is preparation then activation 15 30% w/w zeol...
