摘要： A flocculant composition includes an aqueous solution of a mixture of titanyl sulfate or titanium tetrachloride with a water-soluble, neutral alkali or alkaline earth metal salt at a titanium to alkali or alkaline earth metal salt ratio calculated as TiO.sub.2 of from 0.25:1 to 0.0002:1 by weight. The flocculant composition may further contain a water soluble iron salt at a titanium to iron ratio calculated as TiO.sub.2 and Fe.sub.2 O.sub.3 of from 1:1 to 40:1 by weight, or a water-soluble zirconium salt at a titanium to zirconium ratio calculated as TiO.sub.2 and ZrO.sub.2 of from 1:1 to 40:1 by weight, or a water soluble aluminum salt at a titanium to aluminum ratio calculated as TiO.sub.2 and Al.sub.2 O.sub.3 of from 1:1 to 40:1 by weight. A water-clarifying method includes the addition of an aqueous solution of titanyl sulfate or titanium tetrachloride to raw water in combination with a water-soluble, neutral alkali or alkaline earth metal with or without further combination with a water soluble iron, zirconium or aluminum salt.

摘要： A composition comprises a cellulose acetate or other cellulose ester, and an anatase-type titanium oxide having (1) a specific surface area of not less than 30 m.sup.2 /g, (2) a primary particle size of 0.001 to 0.07 .mu.m, or (3) a specific surface area of not less than 30 m.sup.2 /g and a primary particle size of 0.001 to 0.07 .mu.m. For improving the photodegradability and the dispersibility, the surface of the titanium oxide may be treated with a phosphoric acid salt or other phosphorus compound, a polyhydric alcohol, an amino acid or others. Use of a low-substituted cellulose ester with an average substitution degree not exceeding 2.15 insures high biodegradability. The composition may further contain a plasticizer and/or an aliphatic polyester, a biodegradation accelerator (e.g. organic acids or esters thereof). The degradable cellulose ester composition is highly photodegradable and moldable and hence useful for the manufacture of various articles.
摘要翻译：组合物包含醋酸纤维素或其它纤维素酯，以及（1）比表面积为30m 2 / g以上的锐钛矿型氧化钛，（2）一次粒径为0.001〜0.07μm，或（3）比表面积不小于30m 2 / g，一次粒径为0.001〜0.07μm。为了提高光降解性和分散性，可以用磷酸盐或其他磷化合物，多元醇，氨基酸等处理氧化钛的表面。使用平均取代度不超过2.15的低取代纤维素酯可确保高生物降解性。组合物还可以含有增塑剂和/或脂肪族聚酯，生物降解促进剂（例如有机酸或其酯）。可降解的纤维素酯组合物是高度可光降解和可模塑的，因此可用于制造各种制品。
