in this study, removal of methylene blue (mb) and maxilon blue sl 200% (mb sl) dyes from aqueous solutions by using raw clay (rc) of nevsehir (turkey) vicinity and ultrasonic-acid modified clay (mc) was investigated. adsorption was carried out with 500 mg/l mb and 50 mg/l for mb sl in terms of different adsorbent dosages, contact time, solution ph, temperature and stirring speed. the fitting of...

the silica aerogel was prepared by the acid–base sol–gel polymerization of tetraethylorthosilicate precursor followed by ambient pressure drying. the prepared silica aerogels were characterized by fourier transform infrared )ft-ir(, thermo-gravimetric and differential thermal analysis )tg/dta(, x-ray diffractometer )xrd(, energy dispersive x-ray microanalysis )edx(, brunauer–emmitt–teller (bet)...

zinc oxide nano-particles with the average diameter of about 25 nm were modified with different mole ratios of trimetoxyvinyl silane (tmvs) and oleic acid, as coupling agents, in order to modify their surface properties and render them more hydrophobic. then, dispersibility of the surface modified nano-particles was examined in some monomers with different levels of hydrophobicity, including me...

in this study, modified starch was used as a fat replacer in the milk. the fat replacer was manufactured from modified starch such as pre-gelatinized and cross–linked starches. modified starches were manufactured by hydrochloric acid and citric acid treatments from potato and wheat and were added to skim milk at concentrations of 0.15%, 0.30% and 0.45%. viscosity, total solid, fat content, titr...

the paper introducedeffects of modified pyrolysis tar on flue gas desulfurization. this experiment selected the pyrolysis tar as the raw material, researched the effects on desulfurization performance under different modification solution, concentration, solid liquid ratio of pyrolysis tar and modified solution, calcination temperature and calcination time by 16 group orthogonal experiments. th...

Natural attapulgite modified using acid activation, heat treatment, and organic modification was investigated as a humic acid adsorbent and an optimal modification method was confirmed. Results suggest that acid activation should be performed first and followed by organic modification. Optimum dosage of modified attapulgite was 0.7 g/L and the humic acid removal rate reached 97%. Optimum modifi...
