Sintesis karakterisasi dan aplikasi poli{( 4 vinil piridin) KO (asam metakrilat)} sebagai adsorben selektif ion pb2 menggunakan teknik ion imprinted polymer = Synthesis characterization and application of poly {(4 vinyl pyridine)- co-( methacrylic acid )}as selective adsorbent for pb2 ion using ion imprinted polymer technique
" Imprinted polymer untuk ion Pb2+ (Pb-IIP) disintesis melalui proses self assembly antara monomer fungsional 4-vinil piridin dan asam metakrilat serta ion Pb2+ sebagai template. Kompleks template/monomer yang terbentuk dipolimerisasi menggunakan metode polimerisasi suspensi dengan pengikat silang etilen glikol dimetakrilat (EGDMA) dan inisiator 2,2?-azobis isobutironitril (AIBN). Proses leaching menggunakan HNO3 0,5 M dilakukan pada Pb-IIP hasil sintesis untuk mengelusi ion Pb2+, sehingga didapatkan rongga spesifik yang berfungsi sebagai situs pengenalan. Keberhasilan sintesis polimer dianalisis menggunakan FTIR. ... "

Effect of mixed solvents consisting of water and organic solvent on preparation of medium-responsive grafted cellulose film by means of phtografting
" Cellulose having a medium-responsive function were synthesized by photografting of methacrylic acid (MAA) on regenerated cellulose film (thickness = 20 µm) at 60°C using mixed solvent consisting of water and organic solvents such as acetone and methanol. Xanthone was used as photoinitiator by coating on the film surfaces. A maximum percentage of grafting was observed at a certain concentration of organic solvent. MAA-grafted cellulose films produced showing homogeneous distribution of grafted chains, which was examined ... "
