PENINGKATAN MUTU IKAN ROA (Hemiramphus sp.) ASAP DENGAN RESPONSE SURFACE METHOD-CENTRAL COMPOSITE DESIGN (RSM-CCD)

بهینه سازی پارامترهای موثر در سنتز نانومیله ها ونانوبلت های tio2 با استفاده از روش central composite design(ccd)

بخش اول نانومیله و نانوبلتtio2 با پیش ماده تیتانیم تترا ایزو پروپوکساید(ttip) و به روش سل – ژل سنتز شدند. پارامترهای موثر بر این روش که عبارتند ازدمای محیط واکنش، عامل سورفکتانت، نسبت آب به پیش ماده ی آلکوکسیدی، و ph به روش central composite design بهینه سازی شدند. نقش این فاکتورها به عنوان فاکتورهای موثر بر مورفولوژی نانومیله و نانوبلت tio2و بر اساس تصاویر حاصل از آنالیز sem مطالعه شدند. در ن...

Application of Response Surface Methodology (rsm) – Ccd for the Production of Laccases Using Submerged Fermentation

Laccases are multi-copper oxidases widely distributed in plants, animals, insects and microorganism. These enzymes catalyze the one-electron oxidation of a wide range of organic and inorganic substances, including mono, di and poly phenols, aminophenols, methoxy phenols, aromatic amines and ascobate with the concomitant four electron reduction of oxygen to water. Laccase has the focus of much a...

Optimizing the condition of rearing Astronotus ocellatus using statistical method Central Composition Design (CCD)

This study was designed to determine the effects of parameters: temperature, pH and dKH on growth indices of Oscar fish (Astronotus ocellatus). For this purpose, in each aquarium, there was specific combinations of temperature, pH and dKH, using design of experiment with Design Expert 7.0, and in total 14 combinations or treatments, each with 3 repetitions and thus, 3 fishes were entered in eac...

Design of Dye Adsorption by Amine Terminated Dendritic Functionalized Halloysite Nanotubes Using Response Surface Methodology (RSM)

Response surface modeling of lead (׀׀) removal by graphene oxide-Fe3O4 nanocomposite using central composite design

BACKGROUND Magnetic graphene oxide (Fe3O4@SiO2-GO) nanocomposite was fabricated through a facile process and its application as an excellent adsorbent for lead (II) removal was also demonstrated by applying response surface methodology (RSM). METHODS Fe3O4@SiO2-GO nanocomposite was synthesized and characterized properly. The effects of four independent variables, initial pH of solution (3.5-8...
