    Phosphate-Based Treatments for Conservation of Stone

    RILEM Technical Letters (2017) 2: 14‐19 DOI: http://dx.doi.org/10.21809/rilemtechlett.2017.34 Phosphate‐based treatments for conservation of stone Enrico Sassoni a* a Department of Civil, Chemical, Environmental and Materials Engineering, University of Bologna, Via Terracini 28, 40131, Bologna, Italy Received: 30 May 2017 / Accepted: 09 August 2017 / Published online: 9 October 2017 © The Author(s) 2017. This article is published with open access and licensed under a Creative Commons Attribution 4.0 International License. Abstract To overcome the limitations of currently available protectives and consolidants for carbonate stones (such as marble and limestone), in 2011 the use of calcium phosphate was proposed. The idea is forming calcium phosphates (ideally hydroxyapatite) as the reaction product between the substrate and an aqueous solution of a phosphate salt that the stone is treated with. In this paper, the studies aimed at identifying the best treatment conditions (in terms of nature and concentration of the phosphate precursor, solution pH, reaction time, ionic and organic additions) are first briefly summarized. Then, the efficacy of the phosphate treatment in protecting marble from dissolution in rain and restoring cohesion of weathered marble and limestone is discussed. Some recent studies on the use of the phosphate treatment on alternative substrates and some future steps for research on the topic are finally outlined. Keywords: Cultural heritage; Marble; Hydroxyapatite; Protection; Consolidation 1 Introduction improve mechanical properties, by providing a binding action between the stone grains. Organic products are A great part of cultural heritage objects (e.g. monuments, effective in improving mechanical properties, but again architectural decorations and statues) is made of carbonate they lack compatibility and durability.

Kakkar* Department ofChemistry, Kurukshetra University, Kurukshetra -132119, Haryana; India Key words: vanadium(V), oxine, 8-hydroxyquinoline, gravimetry A very simple gravimetric method for the determination of vanadium has been worked out. In acid medium vanadium is reduced to tetravalent state which forms greenish-black precipitate with 8-hydroxyquinoline (2 % in 2 mol 1-1 CH3COOH) in the presence of ammonium acetate. The precipitate is dried and weighedas VO(C9H60 N)2. The con­ version factor for vanadium is 0.1437. The method is free from the interference of molybdenum(VI), chromium(III,VI), uranium(VI), selenium(IV), arsenic(I1I), bis­ muth(III), lead(U), calcium(II), manganese(I1) and maguesium(II).

H2O /CaSO4.H2O TSP: CaHPO4.2H2O SUMMARY CONCLUSIONS OF THE SIAR Category/Analogue Rationale The category consists of monoammonium phosphate (MAP; CAS No. 7722-76-1), diammonium phosphate (DAP; CAS No. 7783-28-0), ammonium polyphosphate (APP; CAS No. 68333-79-9), single superphosphate (SSP; CAS No. 8011-76-5), and triple superphosphate (TSP; CAS No. 65996-95-4). All members of the category are mainly or exclusively used as fertilizer and have one common functional group (phosphate) that equilibrates between several different ionic species - = = -3 [H3PO4, H2PO4 , HPO4 , HPO4 , or PO4 ] depending on the pH of the environment. Thus, chemical reactions for all compounds in this category are similar with the exception of the actual dissociation product, which forms calcium or ammonia along with common phosphate moieties. However, the presence of the ammonium ion will influence the observed toxicity and its data are used to conservatively represent the toxicity of the category members. Under typical environmental conditions, the phosphate would be present as monohydrogen = - - phosphate (HPO4 ) or dihydrogen phosphate (H2PO4 ) with the equilibrium favoring H2PO4 as the acidity of the environment increases. Under these conditions, the proportions of phosphoric acid -3 (H3PO4) and the phosphate anion (PO4 ) would be extremely low.

    Prohibited and Restricted Chemical List

    School Emergency Response Plan and Management Guide Prohibited and Restricted Chemical List PROHIBITED AND RESTRICTED CHEMICAL LIST Introduction After incidents of laboratory chemical contamination at several schools, DCPS, The American Association for the Advancement of Science (AAAS) and DC Fire and Emergency Management Services developed an aggressive program for chemical control to eliminate student and staff exposure to potential hazardous chemicals. Based upon this program, all principals are required to conduct a complete yearly inventory of all chemicals located at each school building to identify for the removal and disposal of any prohibited/banned chemicals. Prohibited chemicals are those that pose an inherent, immediate, and potentially life- threatening risk, injury, or impairment due to toxicity or other chemical properties to students, staff, or other occupants of the school. These chemicals are prohibited from use and/or storage at the school, and the school is prohibited from purchasing or accepting donations of such chemicals. Restricted chemicals are chemicals that are restricted by use and/or quantities. If restricted chemicals are present at the school, each storage location must be addressed in the school's written emergency plan. Also, plan maps must clearly denote the storage locations of these chemicals. Restricted chemicals—demonstration use only are a subclass in the Restricted chemicals list that are limited to instructor demonstration. Students may not participate in handling or preparation of restricted chemicals as part of a demonstration. If Restricted chemicals—demonstration use only are present at the school, each storage location must be addressed in the school's written emergency plan. Section 7: Appendices – October 2009 37 School Emergency Response Plan and Management Guide Prohibited and Restricted Chemical List Following is a table of chemicals that are Prohibited—banned, Restricted—academic curriculum use, and Restricted—demonstration use only.
