Increasing the content and time of alkali treatment increased the ability of biomimetic minerialization on pure titanium surfaces.

This article describes the prerequisites and mechanism of preparing hydroxyapatite deposited titanium metals via alkali treatment, introduces the effects of the properties of the hydroxyapatite deposited titanium metals by different prepared methods in recent years and gives the evaluation and prospect of this method.

Particle size distributions and its biochemical methane potential(BMP) of the sludge generated from a wastewater treatment plant(WWTP) in Ji nan city were studied in order to learn the effect of alkaline pretreatment on the sludge BMP.

The processes of alkaline pretreatment and hot-water extraction were investigated.

Study on alkaline treatment of PVDF membranes on grafting of styrene

The results showed that the three pretreatments could disintegrate the sludge and the effectiveness of alkaline treatment was the maximum(about 58.

The effects of alkaline treatment and ramie fibers length on the mechanical properties of ramie fibers/Poly(propylene carbonate) composite materials were studied,and the impact fracture morphology of ramie fiber/Poly(propylene carbonate) was observed by scanning electron microscope.

Effect of alkali pretreatment on selective oxidation of cotton fibers;

The results show that unbleached acetosolv pulps have low brightness compared with other pulps, oxygen delignification of acetosolv pulps needs higher NaOH charge, and alkali pretreatment of acetosolv pulps could reduce the consumption of NaOH in oxygen delignification and avoid the serious drop in pulp viscosity.
