“…The presence of Fe 2 P 2 O 7 and Mg 3 (PO 4 ) 2 in B700 was consistent with the XPS results of B700. It should be noted that the dissolution of metaphosphates was always accompanied with the hydrolysis of these compounds, leading to the major released P form of Pyro-P and Ortho-P [26,27], this is why only two species can be detected by liquid-state 31 P NMR.…”

“…In this study, the XPS result shows that metaphosphate and the P associated with C bridged by O (C-O-P) were the main species in biochar. Thus, the polymerization degree (chain length) of the metaphosphate [26,31], the stability of the metaphosphate structure as well as the stability of the organic matters associated with P via the mode of C-O-P in biochar, would also influence the stability and release rates of biochar-P.…”

“…Third, vitreous calcium metaphosphate has the property of forming a two-phase system when treated with an excess of water. One phase is a dilute solu tion of low-molecular-weight phosphates, and the other is a concentrated viscous phase, called "coacervate" by Brown and Lehr (1964), which contains the high-molecular-weight material. A fourth group of phosphorus compounds that was considered contains phosphorus-nitrogen bonds and phosphorus-nitrogenphosphorus linkages.…”

“…A second way of reducing the toxicity might be by lowering Brown and Lehr (1964) observed that treatment of high-molecular-weight calcium metaphosphate with ammonium fluoride yields no precipitate of complexed by the phosphate. Third, vitreous calcium metaphosphate has the property of forming a two-phase system when treated with an excess of water.…”

INFORMATION TO USERSThis maierîai was produced from a microfilm copy of the original document. While the mcst advanced technological means to photograph and reproduce this document have been used, the quality is heavily dependent upon the quality of the original submitted.The following explanation of techniques is provided to help you understand markings or patterns which may appear on this reproduction. I.The sign or "target" for pages apparently lacking from the document photographed is "Missing Page(s)". If it was possible to obtain the missing page(s) or section, they are spliced into the film along with adjacent pages. This may have necessitated cutting thru an image and duplicating adjacent pages to insure you complete continuity. When an image on the film is obliterated with a large round black mark, itis an indication that the photographer suspected that the copy may have moved during exposure and thus cause a blurred image. You will find a good image of the page in the adjacent frame.3. When a map, drawing or chart, etc., was part of the material being photographed the photographer followed a definite method in "sectioning" the material. It is customary to begin photoing at the upper left hand corner of a large sheet and to continue photoing.from left to right in equal sections with a smaii overlap. :î ïseeessary, seetlorssrsg is continued again -beginning below the first row and continuing on until complete.4. The majority of users indicate that the textual content is of greatest vaiue, however, a somewhat higher quality reproduction could be made from "photographs" if essentia! to the understanding of the dissertation. Silver prints of "photographs" may be ordered at additional charge by writing the Order Department, giving the catalog riurnuër, tltââ, author and specific pages you wish reproduced.5. PLEASE NOTE: Some pages may have indistinct print. Filmed as received.
