Abstract
Solubility, adsorption onto mineral particles and entrainment of 2-chl oro-4-(1,1,3,3-tetramethyl-butyl)-6 methylol-phenol (CTMP) in aqueous slurry phase are considered here. The results show that, the solubilit y at equilibrium increased sharply with pH, but remained at only 16 pa rts per million (ppm) at pH 9. With regard to adsorption onto various mineral phases considered, the affinity for CTMP increases in the orde r quartz < clay minerals < carbonates. The adsorption is about 9 and 1 3 ppm for quartz and bentonite respectively. The entrainment at pH 9.2 is about 107 and 110 gm(-3) for bentonite and the Kirka slurry respec tively.
