The physicochemical properties of organo-silica xerogels derived from organo catalyst were pervasively investigated, including the effect one-step (citric acid) and two-step (acid-base), also to observe sol pH xerogel toward structure deconvolution characteristic. characterized by FTIR, TGA nitrogen sorption obtain properties. silica sol–gel method was applied processed materials employing TEOS (tetraethyl orthosilicate) as main precursor. final molar ratio 1:38:x:y:5 (TEOS:ethanol: citric...
Cr(vi) is a heavy metal with high toxicity level. Many levels of in the environment are above established quality standards. The membrane filtration method technique that can be used to reduce because it more effective and efficient compared other methods. In this research, ability PES integrated boehmite nanoparticles coated polyphenolic compounds from Samanea saman bark extract (mixed matrix hollow fiber PES/B-polyphenol) was studied reducing levels. removal carried out research module, so...
Dialysate fluid is a vital component in hemodialysis therapy. Processing and reusing spent dialysate significantly reduces costs produces environmentally friendly hemodialysis. In this research, mixed matrix membrane adsorbers (MMMAs), which have the potential to recycle dialysate, been developed. MMMA composed of cellulose acetate (CA)-based polymers synthesized from isolated oil palm empty fruit bunches (OPEFB) integrated with silica (Si) bio-adsorbent rice husk ash waste. The was cast...
Polyethersulfon (PES) membrane has been widely used in the biomedical field especially hemodialysis application. Many modifications of membranes have applied into such as diffusion, adsorption, and mixed-matrix membrane. The main problem those is less selectivity to attract uremic toxins. In this study, we report modification PES mixed with cellulose acetate (PES/CA) (MMM) using imprinted-zeolite (PES/CA/IZC) order increase for targeted analyte. hollow fibre (HFM) were fabricated by dry-wet...
Inorganic-organic composite membranes (IOCMs) are an alternative separation method developed for their straightforward process, economic benefits, and ease of scaling up. The IOCMs in this study were prepared from a biopolymer chitosan matrix rice husk-based silica filler to remove impurities crude biodiesel. through phase inversions, which the priorly particles dispersed dope solution chitosan. maximum loading was 60%, capable reducing soap level, free glycerol acid number 547.9 12.2 mg/L,...
The adequacy in uremic toxin removal upon hemodialysis treatment is essential patients with kidney failure diseases as poor leads to heart failure, hypertension, and stroke. combination of adsorption diffusion processes has become very advantageous for membranes. By this mechanism, water-soluble toxins (WSUTs) protein-bounded (PBUTs) could be removed at one time. Therefore, study aimed develop a novel imprinted zeolite by p-cresol (IZC) then incorporated it into polyethersulfone (PES)...
A liquid-phase microextraction coupled with LC method has been developed for the determination of organophosphorus pesticides (methidation, quinalphos and profenofos) in drinking water samples. In this method, a small amount (3 microL) isooctane as acceptor phase was introduced continually to fill-up channel 1.5 cm polypropylene hollow fiber using microsyringe while immersed an aqueous donor solution. portion (ca. 0.4 first into additional amounts 0.2 were replenish at intervals 3 min until...
Abstract Coating method and number of membrane layer are crucial factors on performance. Through a vacuum impregnation allows sol solution uniformly fill into support it is required only less solution. The aim this study to apply through calcination air during fabrication silica membranes investigate the effect variations performance for brackish water. was made from TEOS as silane precursor, ethanol dual catalysts (citric acid + ammonia). Alumina coated by calcined under condition. From...
Zeolites were added to polyethersulphone (PES) membranes in order enhance their capability of attracting creatinine.Zeolite was blended with PES by varying its doping concentration and time, the mechanical properties resulting hollow fibre produced under optimal characterised.The values tensile stress, strain Young's modulus, as well flux rejection determined.
The adequacy of uremic toxins removal via hemodialysis treatment is essential for every kidney failure patient. To obtain adequacy, the effects main polymer were investigated. hollow fiber membranes produced by using dry/wet spinning process from dope solution comprising PES as polymer, 3% poly(vinyl pyrrolidone) (PVP) in 1-methyl-2-pyrrolidone (NMP) at 40-cm air gap. loadings 14, 16, and 18 wt.% studied. membrane morphology was characterized a scanning electron microscope (SEM) properties...
Hollow fiber membranes of polyvinylidene fluoride (PVDF) were prepared by incorporating varying concentrations hydrophilic surface-modifying macromolecules (LSMM) and a constant amount polyethylene glycol (PEG) additives. The fabricated the dry-wet spinning technique. hollow dip-coated hydrophobic (BSMM) as final step fabrication. additives combination is aimed to produce with high flux permeation salt rejection in matter seawater desalination application. This study prepares from...
Salah satu upaya pemeliharaan kesehatan pada masa darurat seperti pandemi Coronavirus Disease 2019 (COVID-19) saat ini dapat dilakukan dengan memanfaatkan bahan-bahan alam untuk diolah menjadi obat tradisional. Jamu sebagai salah jenis tradisional sekaligus warisan telah dimanfaatkan secara luas oleh masyarakat Indonesia mencegah penyakit dan merawat kesehatan. Kegiatan Pengabdian Kepada Masyaraka (PKM) bertujuan memberikan edukasi kepada terkait kandungan kimia khasiat empon-empon serta...
