    Interest in the biosynthesis of silver nanoparticles (AgNPs) has been steadily increasing primarily due to their numerous applications in various fields, low-cost, use of non-toxic environmentally-friendly materials and easy implementation... wavelength of 403.8 nm in UV-vis spectra, and minimum particle size of 12.9 nm. In addition, peak absorbance and SPR wavelength appeared to be related to the size of the AgNPs. A full-factorial design for the catalytic degradation of MB dye

    Blood cockle shell: an agro-waste for N and P removal of shrimp farm effluent
    (2013-06) Mothinee Aopreeya; Chumlong Arunlertaree; Chumporn Yuwaree; Rattana Boonprasert; Rungjarat Hutacharoen; Rungjarat Hutacharoen; Mahidol University. Faculty of Environment and Natural Resource Studies
    ) blood cockle shell (grinding, NBCS). All shell types (BBCS, NBCS) performed well as adsorbents The removal efficiency varied with shell particle size and effluent flow rate. The shell particle size of BBCS at 0.85-2.0 millimeters had the highest... and Teller method: BET) produced more N and P removal efficiency than the lower one as NBCS.
