The results show that the best fining effects are obtained at pH 4 with 0.04% tannin and 0.02% glutin,or with the ratE of bentonite,glutin alum is 0.1%,0.01%,0.015%.
By using the orthogonal design method,the authors optimized the formula of compound quality improver for producing wet noodle from middle gluten flour as follows:starch 5%,alum 0.5%,CMC 0.2%,sodium alginate 0.2%,monoglyceride 1%,salts 1%,soda 0.2% and mixed phosphate salts 0.2%.
This paper has summarized the researches on the application of such mineral materials as activated carbon,zeolite,montmorillonite, sepiolite, medical stone,palygorskite,aluminum oxide,sodium hydrate,alumen and nanomaterials as cigarette tip additives to the removal of harmful components in cigarette smoke in the last decades.
Environmental and ecological engineering on control and remediation of eutrophicated waterbodies: by using ameliorated alum plasma and fishes to control blue-green blooms of qiaodun reservoir
The emergency dealing with the "bloom" by insufflating ameliorated alum plasma of 55.6 g each square meter of water was carried out in Aug. of 2000 and the "bloom" disappeared that year.
As a further precaution against distortions in the emulsions potassium alum hardener has been added to the fixing bath, and the emulsions were dried slowly at a temperature below 10 ?C.
The absorption spectra of hematein-aluminium solutions have been recorded at various concentrations and pH values; the solutions were prepared using analytically pure hematein and potassium alum as aluminium source.
The Fe3+-spin in alums of type (Fex, A11-x)NH4(SO4)2 · 12 H2O interacts (i) with the crystal lattice viaLS-coupling, and (ii) with the spins of the adjacent Fe3+-ions via magnetic dipole-dipole interaction.
The times may be deduced from the57Fe-M?ssbauer spectra of the alums, τc from the width, and τ'c≈τc from the position of the hyperfine structure lines.
1.The efficacy of alum-precipitated vaccine produced from Beef Liver Infu- sion Broth was 8-15% higher than the formal-whole culture vaccine produced from the same medium,and 51% higher than the formal-whole culture vaccine prepared from peptone beef liver broth of USSR formula. 2.The rate of protection on guinea pigs by alum-precipitated vaccine and formal-whole culture vaccine was 93% and 42% respectively;but on cattle was 91% and 75% respectively. 3.Usiug guinea pigs,the efficacy of alum-precipitated vac...
1.In comparing the immunity of several lots of alum-precipitated vaccine prepared from beef liver infusion broth by cultivation for 2,5,10,15 and 20 days,the 2 days culture has been found most satifactory. 2.The efficacy of the vaccine on guinea pigs was influenced by the body weight.The lighter group showed higher protection. 3.The immunity in sheep began at 72 hours after the inoculation with 2 c.c. of alum-precipitated vaccine and it become solid after 124 hours. 4.The vaccine kept at a temperature of 10...
(1) Large amounts of Cl. perfringens type C toxin could be produced when the organism was cultivated either in liver broth or in two types of modified V. F. media. (2) Liver broth which contained 10-40 per cent liver pulp (w/v), proved to be more suitable for the production of Cl. perfringens type C toxin in 16 hours of growth. (3) On comparing the potency of the formalized, alum precipitated, and aluminum hydroxideadsorbed vaccines on sheep and rabbits, results were as follows: when the vaccinated animals ...
